In terms of lighting, you have two factors you want to get right: heat, and UVB.
So far, I'm not sure with this bulb you're hitting either of those right. You haven't submitted any measurements for what the temperature in your terrarium is yet. I know you don't have your plant yet, so that might be difficult. You need to properly measure the temperature at your chameleon's basking spot, and then the ambient temperature in the cage. There should be a gradient so he can move up and down and from side to side to find where he's comfortable, and you don't wan the basking spot too hot. Secondly in terms of UVB, you need to have the right AMOUNT of UVB. On these forums, and other places, experts will tell you that UVB 5.0 is ideal for chameleons. For this bulb that you have, which I'm not familiar with, it only says what the wattage is. I can't find any information on Exo-Terra's website or anywhere else that says how powerful the UVB on the bulb is.
"Optimal levels of UVB, UVA, visual light and heat in one bulb
Self-ballasted mercury vapour bulb
Provides the benefits of natural sunlight
Helps prevent metabolic bone disease
Increased UVB penetration distance (+30 cm)"
That really doesn't mean anything to me, and it shouldn't to you. Too much UVB can literally make your chameleon go blind, and too little and he'll develop deficiencies.
The other thing you'll need to think about is drainage for the drip system, which it doesn't look like you have setup yet.
Otherwise you are good. I hate the mesh cages personally, but you're not putting him in an aquarium so you're good there. You're getting live plants, good grades there, and you've got vines and fake plants too. Good to go. The fogger I don't really think is necessary unless you live in a really dry area and humidity is a problem, but it probably won't hurt either.
