those sound like pretty easy things to teach!
i taught Zoey to stand by simply putting her in a down, then holding a treat just in front and above where she could get it, and when she stood i click/treat. then start moving it back farther so she stands up quicker, put in a hand movement or a word for it, and there you go! i'm sure someone else can do a better job at explaining it haha
as for looking up to avoid sniffing? i'd teach a "leave it" or "watch" so when you say it he looks up at you. Zoey's a sniffer when we go for walks, and that's fine kuz she's exploring and having fun, but if she heads towards something i don't want her getting into i use a leave it. i also use it when she's chasing my cats, or thinking about it...
Good luck! those seem like pretty simple things to teach, i'm sure you guys will have it in no time :)
