It really does depend on the tracks, but I generally will get a lot of my reverb by taking the room tracks and smash the bejeezus out of them, then blend that in underneath. I usually buss the toms to a group and put a bit of my short verb on them. The kick usually gets a bit of the short verb. The snare generally gets the short verb and a fast fat plate - sometimes I add a bit off my longer verb. Sometimes I'll buss everything to a group and just verb that, or sometimes I do the above then buss and add a touch more plate, or short verb, or sometimes a tiny bit of the big verb - although I have drowned the buss in a big long verb - I did a Rob Thomas cover that required that - cant think of the name of the song, but it starts out with just the drums.
There are about a million different ways to go. teh best thing is listen to how the song sounds, think about how you want it to sound, figure out what's missing or excess, and either add or remove what's needed. It ain't rocket surgery.
