Slickrock trail is the classic bucket list trail in Moab. It's not especially technical but it can get very hot - seen a number of people bonk or get heat stroke on it.
Porcupine rim is another classic, but more technical.

I like mtbproject.com for trail maps. They have a decent Iphone app as well.
