Good luck doing the drums seperately!

I'd invest in a small mixer and mic up to 2 tracks (left and right)...a kick and snare mic and two large capsule condensors overhead, that'll pick up the toms aswell...
Failing that, get 2 decent mics, get the kit sounding decent, and play around with mic placement to get a real drum sound...a lot of recordings in the 60s probably had one mic on the drums!! Slam a compressor on a single mic and a bit of eq and you will have a deadly drum sound, you could overdub some single hits of the snare to their own tracks to tighten up the beat when everything else gets louds (ie. choruses, or the middle 8)
