The guidebook you want is "The Dome Driver's Manual". It's a very cool little book. You ought to be able to get it at most gear stores in Texas (there are REI stores in Dallas, Austin, and, I think, Houston, and there's a Whole Earth (IIRC) in Austin that's very good).
I haven't climbed there very much but it seems to be mostly slabs with minimal to decent gear, depending on the route, and the occasional bolt. We did a few easy climbs (including Dome Driver, which was just plain terrific) that seemed a bit runout.
Cool place. I'd like to climb there more.
