I recommend getting at least one live plant. They hold water better and longer for your cham to drink. They also provide humidity pockets. I recommend a linear UVB or a compact that is in a horizontal dome. I would ditch the green carpet, those can get nasty, and are a pain to clean sometimes. (If you get a live plant, you can have the dripper drip over the pot to minimize insects drowning or an accident with your chameleon. Plus, if your chameleon poops in the cup of water, that will breed bacteria.)
