I have the SHURE 4-piece kit as well. I like it lot for my 6 piece. I use 1 on the snare, 1 between my 2 floor toms, 1 between my rack toms, and of course that beautiful kick drum mike. It's awesome. Haven't recorded seriously with the mikes, but they are awesome live. If I had the cash, I get individual mikes for each tom.
For overheads, I have 2 SHURE SM-57s, but only use them in larger settings or when we play outside. Inside small bars, my cymbals are loud enough.
Oh, BTW, if you have something like a floating-tom system (a la Ludwig's Vibraband), the clips included in the SHURE pack are a pain.
