I highly recommend Robert Zubrin's "The Case for Mars" - you'll be surprised what else is possible on Mars with current technology:

Also, TA Heppenheimer's Colonies in Space has a dandy compilation chapter on research on agriculture in enclosed environments. ("Up on the farm")

http://www.nss.org/settlement/ColoniesInSpace/colonies_chap0...

Most of what's talked about in that chapter will also be possible on Mars.
