If I had that equipment for a basics session I'd go with something a little less standard...

Kick - RE-20 or 421 (try both)
FOK - AT4047
Snare - Audix
Hats - Notta. Maybe an SM57 if someone puts a gun to my head.
Rack - SM57 or 421 (try both)
Floor - 4047 or D112 (try both)
OH - 4033 in mono
Room - SM57, T3 (never used one, why not try it?) or even both.

Pick your pres and stick with 'em. Swapping mics will make a bigger difference, though if something really isn't sounding right swapping preamps around might help. I'd also stick the Behringer converters on the toms.

Part of that dry 70's funk drum sound comes from tracking in small, diffuse, really dry rooms. A larger part comes from tuning the kit so it makes that sound before you touch a microphone. Ask around about head & tuning choices and don't forget to put a wallet on the snare drum! Duct tape is evil stuff for damping tubs, use real gaffers tape or better yet, get some Moongels from a drum shop.
