I built and sold a bike w/ a shift kit and 3 speed hub and built one with a shift kit and 7 speed derailer. In my humble opinion, any more gears than 3 is more than you'll need, owever, a rear wheel w/ derailer is much less expensive and easier to come by than a 3 speed hub.
Oh, and btw, the bike I built had a 3 speed Shimano Nexus hub. The hub didn't last a week before it turned to mush. If the Sram I-motion 3-speed hub is as good as people here have said, and you can afford it, I'd go with that!
