Well, I think there is a bit more info than what Tony told you. he made it sound that they are easy. They are high maintenance and expensive to keep - but they are delightful! Yes, I would think that your climate would be conducive re: the humidity and temps. Can you keep them outdoors all year? Many of the folks on this forum live in climates where they can do it and are always willing to share cage plans, misting units, etc. so you may want to post with specific set up questioens as well.
As for UVB - if you can give them "real" sunlight (not thru a screen or window) that is the best. A good quality UVB light for 10-12 hours/day is the next best. I linked an article below on calcium/d3/UVB
In the meantime, check out these sites for some great info - especially ChamNews. be sure to look at their earlier issues and articles:
