Treating the basement as unconditioned per code, find your zone here;http://publicecodes.cyberregs.com/icod/irc/2009/icod_irc_2009_11_par002.htm

Insulation for floors- per zone, here; http://publicecodes.cyberregs.com/icod/irc/2009/icod_irc_2009_11_sec002.htm

Vapor retarder goes toward the warm side- up. If the basement is dry/drafty, you could cover the f.g. with a housewrap on the joist bottoms to stop air infiltration from degrading its R-value, treating it more like a crawl space; http://energy.gov/energysaver/articles/where-insulate-home
Keep in mind you may create problems with the plumbing/ducting uninsulated and colder without the heat loss from above warming them as it does now...
