Thanks to all for your responses. This has been a great "thinking out loud" forum for us. It's really been helpful. The first band we are taping in this new venue is Donna The Buffalo. We all know the keyboard player fairly well, and they are very taper friendly. Since they don't play loud, hard rock, the onstage sound should be very good.
To my knowledge, they don't use IEM, but I could be wrong there. I think that if we can concentrate our efforts on getting a good onstage feed from a pair of omni's, combined with a good direct PA miking, and a board feed, we should be able to pull a very good recording.
Now to get a good video cam......
