I don't know but the way you put everything made me laugh. I will try to answer a few questions. 1. the black and white reflective/material you want is called Panda film, it's black and white just like a panda. You get it at your local garden or hydro store or online of coarse.
2 there are zippers that you can get for the film or other materials and they are called "Pill and Stick Zippers" Just the way it sounds, they are about 7 to 8ft and you pill off the adhesive tape and stick to the area that you cut out for a door then presto, you have a door that you zip up and down to open. 3. fan, you can do what your saying, attach a fan to the top of the board and it would probably work, but the power of the fan is going to depend on how intense the lighting you want is going to be.
4. CFL's are going to work and there are fixtures that you can buy at Lowes or Home Depot that have a hood around the fixture with a clamp that could attach to say a curtain rod in the shower and they have a plug in. Also you could get a couple 4 , 3 or 2 foot T5 high out put florescent lamps that could stretch across the whole shower.
To help out more I would need to have an idea of how much personal smoke your trying to produce. You say you don't want to use HID lighting, but you can get to a certain point where you are using just as much electric on florescent lighting as HID.
hope this helps.
