Looks pretty good so far; the drums are going to be the trickiest for you, I suspect. (Can you live without tom submixes, etc. etc.) The type of music and sound of the drums will help you make these decisions, most likely.
Don't rule out a live stereo capture of the band in the room (esp for audience reactions, applause, etc.) I hate so called "live" recordings that make it sound like the audience was out in another room somewhere, because no one thought to put up ambient mics on the room itself. Even if you only bring the appluse up and down for ins and outs of songs, it's far far better than leaving it out entirely. (This is the whole point of a live recording, yes? )
Perhaps you can track the stereo live mic on a portable recorder and sync it up later. I use my M-Audio MicroTrack II for this sort of thing from time to time, esp if I run out of tracks, or have to use a completely different feed.
And speaking of a two track recorder, make sure you run a safety overall stereo mix of the whole thing as well. YOu never know when that will save your butt should the multitrack crash or a channel drop out, etc. etc.
Good luck; sounds like a fun gig.
