I agree with corgipower 100%. I don't allow growling at people. Or lip curling. If he can't be nice about sharing the bed, then he doesn't get to share it. Since this behavior is moving into other areas and you're concerned about it, it seems like it will only progress. NILIF can be fun. It SHOULD be fun. You don't have to be a big jerk to let your dogs know what the rules are. It's a positive thing. They like to have boundaries and know where the limits are.
I also strongly believe that all dogs are aggressive under the "right" circumstances. Gotta be aware of what those circumstances might be, what your dog's comfort zone is, and then make sure he's never put in a situation where he feels he has to test those behavioral boundaries.
Also, if he's being growly at all, DO NOT MOVE HIM BY HIS COLLAR. If he is going to be aggressive, this is a common way for people to get bitten. Either keep a leash on him and guide him with the leash or get him to move off some other way. (I taught my dog a quick and easy "off" command for this purpose: *throw treat on the ground* "Off!" *dog follows treat* -> "Off!" *dog jumps off* *throw treat on the ground* - took us like 5 minutes.)
To me, it sounds like your dog is "resource guarding" his comfy place on the bed. It sounds like he's saying, "Hey, this is my spot, and I'm comfy here, so go away!" I think NILIF would be extremely valuable for you.
And, at least for now, don't allow him on the furniture at all. Better he suffer a bit by having to sleep on his own bed than someone gets bitten because they accidentally rolled over on him in the night, right?
Don't be too concerned, it's not a huge problem right now, but a bit of extra training now will make your lives MUCH easier later on!
