I personally say ditch the red bulb, especially if you were told it is a bulb for night time use (like I was early on, and was quickly corrected). Also, you will need a uvb bulb, preferably the bar style bulb over the compact florescent or CFL bulb.
I go through a lot of water to keep my humidity up, but I have a Jackson, and it looks like you have a Vieled, which has different humidity requirements, but something you should invest in, like I have seen others recommend is a good drip system for watering. I rarely do thing the easy way myself, so I made my own rain system that I have set up on a timer to rain for 15 minutes every 2 hours that I made out of submersible aquarium pump, some tubing, and some garden sprinkler heads, along with some rubbermaid tubs to hold my clean and dirty water, and an aquarium heater to keep the water at a decent temperature. I double this with a Reptifogger that runs all day, and for good measure, I put a Big Dripper to use as well. Overkill? Probably, but Weirdo (my Jackson's) seems to love it.
Don't worry about doing something wrong, we all have. The problem comes when good advice is ignored or worse, taken as an attack. When that happens, the only thing you can expect is a sick or dead chameleon on your hands. We all want what is best for our animals.
