Well, Since I'm the dissenter I'll go ahead and say it - I'd buy something other than the SM57. You basically have one, it's the SM58. There's not a whole lot of difference between the two mic's.
I would put the Money on
an Audio Technica Pro-25.
As for recording with a minimal amount of Mic's.
Rule #1. Tuning is EVERYTHING.
Place the B1 on a Boom Mic stand directly over the drummer's head, and aim it straight down.
Build a "tunnel" in front of the kick drum using blankets and a chair or a garbage can - anything that will allow you to layer several layers of blankets over the end of the kick drum, and leave an open area under there.
Make sure the kick is sounding good out in front, before you build the tunnel.
Then put the other condenser mic under the tunnel.
Then mic the BODY of the Snare from about 8" away with the SM58 - just aim it at the middle of the snare shell from under the hi-hat.
Before you start EQ'ing anything - make a test recording of the kit, and listen back to it. Adjust the mic's positioning prior to making any EQ adjustments - always try using mic placement first. just by moving the mic 1" or so, you can make major changes in the sound.
The snare mic is just to add "fatness" to the snare, as well as allow you to add a little reverb to the snare by itself if you wish.
Typically, I just roll off some of the mid's using this type of mic'ing technique.
Granted - this isn't going to yiled the heavily processed "Radio friendly" (which is typically triggered anyway) drumsound, but it will give you a good solid "Rock" drumsound - as long as the drumkit is tuned well.
Any decent drummer (one who plays with dynamics) will be able to deliver a "pre-mixed" recording since they "mix themselves" according to what they are hearing - this overhead technique basically pics up something similar to what they hear.
