For an enclosure: You'd want something with some airflow (basically, not an aquarium). As for enclosure decor: You'd want a tallish plant in there, with varied sized branches. Maybe a couple of cool lookin' ferns. Mist heavily in the morning, than heavily about 1 1/2 hours before the lights go out. As for general advise, make sure you LEAVE THE ALONE when they arrive. I'm sure they'll be stressed out! As for food, young crickets, roaches, and grubs should be fine.
How many are you getting?
Edit: I didn't answer your question! As for temperatures, ideal day time temps would be 21-23 degrees C, and night, 18-16 degrees C (I believe that's about 75F day, and 67F night?)
