I commend you for doing your research before hand. Cham's are expensive and relatively high maintenance pets to keep, but with the right info, species choice and husbandry you, and your cham, will be happy that you cared enough. Cham News (joe gave you link) has an article on the true cost of cham keeping - check it out.
Check out John's (Charm_Paradise) 5 most FAQ and his Do's and Don'ts list as well. He also has info on plants, etc. As you do your research feel free to the folks on this forum to help clarify info and/or help out in info you simply can't find.
Have fun!
