Corvus, I started out with Sequoyah being a "frenzied" dog, not just over food, but everything LOL. This is a dog so reactive that if you blow on her, she flies off the couch. She would grab food, she would snark at the other dogs when I dispensed treats. I had trouble, at first, using a hand signal, because she would want to "herd" my hand. But, through clicker training I now have a dog that sits nicely with the others and will "wait" her turn, no longer moves about like a jumping bean when I ask for sit/stay. I think the point you may be missing is that the click ends the behavior, and it's at that point that the dog is being told, "yup, that calm thing was what you got clicked for". So, the object, even if the dog is crazed at first, is to click only for the dog being quiet and calm. Personally, if I had to sit for twenty minutes waiting for a coupla seconds of calm, I would do that, then C/T. Sooner or later, the dog begins to realize that it is being clicked and getting the food ONLY when it exhibits quiet and calm:-) As soon as this realization is made, you can begin to wait a sec before clicking, then gradually extend the time she must be calm before you click (duration). When you reward this dog, don't hand her the food, toss it on the floor, away from you. She then has to go get her reward and will come back (maybe in a tizzy again, but the object is to wait her out again until she's calm so you can click.) You first work on the calm, then once she's being calm in all situations when food is present (fluency), you can start to teach "easy" so that you will be able to deliver a food treat by hand.
One behavior at a time. 
When you are not working on "relax" or whatever cue you plan to use for this calm behavior, you can train her with praise or toys. If you want to change the food obsessive behavior, you click only when she is NOT obsessing (even if it takes an hour to notice that), and, wonder of wonders, she gets the object of her obsession! The motivator is what the DOG wants, but the way she gets it from you is now different. She has to be calm to get the reward. Anything else she does, you ignore. If the "anything else" stops working to get her the food, she will stop that and do what does work. Honest.
As to whether you need a reward that is fast, the answer is yes and no. It needs to be fast enough that the dog understands it is the reward for the clicked behavior, but it doesn't need to be so fast that the dog is nipping your fingers in expectation. That's why I suggested tossing the reward on the floor. It keeps the dog away from your fingers, and sets up the next repetition. I think that you can safely suspend training other behaviors until you get the dog calm in the presence of food. That should be job #1, so that you can be comfortable using the method to train other behavior. If you associate a cue, like "relax" once the dog is being calm for a long period, and not getting grabby with the food, then you can use it to prevent escalation.
What she said. I have a dog right now that salivates at dinner time. She does the front-feet-dancing-jig if she thinks what you have is for her. She begins to salivate if you even open a plastic bag. If you're opening a baggie, she thinks its for her and comes running from where ever she is in the house. She pees so fast in the morning because she knows first pee is followed by breakfast. This is Pepper. She will take your fingers off if you're holding a 4 inch biscuit at the farthest end from her mouth.
So yes, I understand food obsession. Pepper came to us as a constant companion if we're eating at the table. We never feed from the table but she came this way and after 5 years, she got her first reinforcement that it's a good thing last night. BF dropped a chip and didn't dive for it before she got it. 
So with that said, what I work on with her is exactly what Anne said above. Calm around food first. She has to think before she can get the food. In the morning, for her biscuit/kong/rawhide in her crate, she must wait patiently and any movement towards the object results in penalties in that I move the object back. The first few times I tried this, it took several tries before she would ignore it long enough for me to put it down on her mat in the crate. This morning, it took only 3. Progress!!! I don't want her snapping my fingers off, so she must wait for me to put it down before she can have it.
In clicker sessions, I simply wait for her to be calm, then I click and either treat her or throw it like Anne said. Depends on what I'm doing with her. I do have to give her the "gentle" so that my fingers remain intact but we have made strides with that as well in that she does not get it (and I endure the pain) unless she is soft with my fingers. And in the heat of agility fun, she still gets too excited and will hurt me with her sharp front teeth occasionally. I have modified how I give her treats to lessen this.
Kota on the other hand, if jazzed up, will run through his entire repertoire of tricks trying to find the right one to earn the treat. I simply wait this out, ask for the behavior again, then reward when successful. The run-through-as-many-as-I-can-to-earn-the-treat does not get rewarded. It might get a laugh, but not the treat.
If you have to lure a down every time, then you have not faded it well enough and she does not know what the cue means yet.
The protocol I use with a new dog follows.
Step 1
Kneel on floor with her.
Put food in your hand
place hand on floor with food in fist and palm down
once she goes into a down, click and turn hand over immediately
repeat until she goes into down reliably every time you put your hand on the floor
Then Step 2:
Kneel on floor with her.
Put food in your hand
Say your cue "Down"
pause for 1 second
then place fist on floor as before
once she goes into a down, click and turn hand over immediately
If she's been reliable in the first part, she should immediately go into a down when you place your hand on the floor. Continue this several times with the cue preceeding the fist on the floor. This is making the association between the "new" cue (the word "down";) and the "old" cue, fist on floor.
Then Step 3:
Kneel on floor with her.
Put food in your hand
Say your cue "Down"
pause for 3 seconds
then place fist on floor as before
once she goes into a down, click and turn hand over immediately
Chances are good that once you advance to this stage, she will go down once you say the new cue. This is not a thing that can be done in one session. Each step will probably take several sessions each. But with this progression, the next step would be to extend the length of time between the new cue and the old cue and gradually fade out the old cue completely. Once the old cue is faded, then you begin to generalize to you sitting on the floor and saying it. Then squatting on the floor, then kneeling on one knee, then standing.
The first 3 steps will take the longest but the rest should go faster because she will understand better. If at any time, she does not go into the down, take one step backwards to the previously well known level of understanding. Do this ONE time then try again. If she fails more than once, then you've probably gone too far or some other criteria has been changed as well and it was too much. It's hard and takes some practice to get the timing right.
