What an amazing place, couple suggestions but most of the park literature will guide you on what you need to see...
Portal RV park, top notch great location in Moab.
If there was one thing I would not miss while in Zion would be the hike through the narrows. It requires special gear that is well worth the cost of the rental. Google the narrows hike and it will get you started.
Renting a jeep in Moab is also a blast, there are several awesome 4x4 trails that will take your breath away. Or if you have little 4x4 experience take a guided tour with Dan Mick, he is the man as far as tours and information.
A great side trip is to a place called Cedar Breaks outside Bryce Canyon. its in the area and great for a day trip to drive there.
If your going in that time frame it may be busy due to the pumpkin chucking event in Moab. Plan accordingly.
