Well... I guess I should congratulate you first on getting a new pet. Welcome to the chameleon addiction! LOL
Wow... umm... what tips can I give you? I have about a bazillion! I could write pages and pages of chameleon information for you, perhaps be a bit more specific with your questions and I'll be glad to help you out.
Otherwise, get a male. They tend to be larger and more colourful, and don't have the breeding issues that females do. Both sexes though are terribly grumpy in this species and for the most part DO NOT want to be held. They are considered a display animal. If you are looking for a lizard that you can hold everyday, a chameleon is not the best choice.
