I agree mostly with Wendy - why don't you spend all your time in the Valley?
I have been to Moab a couple of times now, and although it is a really cool place in terms of landscape, unless you are climbing 20 cracks (and I mean cracks - not face routes with gear), then I wouldn't bother. There are two worthwhile types of climbing in Moab - crack climbing (probably the best in the world) and desert tower climbing (meh). All the other climbing is just not what you fly around the world for. You can have great day out on a desert tower but its about the adventure and getting to the top of something, not particularly great climbing.
Also the gear. If you do decide to go to Indian Creek then you'll need quadruples of hand sizes. The hand cracks are the 'easy' ones and on the classics you'll need a lot of the same/similar sizes.
Unless you plan on getting spanked at the Creek I would stick to Yosemite. You'll jizz in your pants just driving into it.
