you asked for it

The first 2 are very good...the second and third are more family friendly trails.

a book called "Above and Beyond Slickrock" by Todd Campbell is the mtn. bikers bible of Moab (check out amazon.com) There are also several Falcon guides available for hiking and biking in the Moab area.
Also a couple of guide books by Michael R. Kelsey are nice for hiking trails and history (Hiking, Biking and Exploring Canyonlands N. P. and Vicinity is a relevant one)

Also read "Desert Solitaire" by Edward Abbey for some perspective

Plenty of homework for you...enjoy!!
