Magnum - to respond to your original question: For gigs; I mic the snare and bass drum with dedicated mics and then I use two overheads to catch the entire kit. The four cables go into my mixer and out to whatever; PA, board, etc. I place the two over-heads together on a 'Y' stand and point them in an 'X' pattern over the kit. They pick up the brass and the toms perfectly. With rare exception (depends on the room and sound system,) I always get a well-balanced sound coming out the other end. For recording, everything gets mic'ed individually with the snare drum getting two mics, one over, one under the drum. For gigs, two to four mics will do the trick.
Don't worry about 'coming back' after a long lay-off from doing gigs. I went through the same thing two years ago. I was nervous enough to puke before that first gig, but it really is like riding a bike. As long as you're prepared as far as comfort zone with the material... it all comes back to you. I relaxed during the first number and it's been fine ever since. That first gig was a bee-atch on my nerves though. I have to cop to that. I was scared $hitless until we got on stage and started playing. After that... cooley-cool.
Break a leg. Best of luck with your sale.
