I don't have FPSCX10 yet, but I'll try to answer some of your questions anyway.

You NEED to have a DX10 compatible GPU. Any GPU NOT DX10 compatible will NOT run FPSCX10. The NVIDIA 8-series (8400, 8500, 8600, 8800) and the ATI 2000/3000 series are the only cards that will run X10 so far. ATI cards are having some driver issues though, so NVIDIA is probably the way to go. Some people have 8600's, and they getting decent frame-rates, but with most effects off. I'd recommend an 8800.
Quote: "This may seem like a stupid question but anyway - can you use your own models for the games u make, specifically weapons"
Yes, but to do so you'll need to follow some (relatively) simple steps. Don't ask me what they are, as I said I don't have X10 yet so I wouldn't know. Also, some models have had random glitches in X10, you'll have to find a way around them.
Quote: "dows anyone know of a cheap or free modeling programme i can get that can make models that will react to the lighting in the game"
It doesn't matter what modeling program you use, it's X10 that renders the model. The program should be able to export to the DirectX file-format (.x), though. I do know that Jon and Bond use 3ds Max, but that's probably way above your budget, so I would look for a cheaper alternative.
Quote: "Do you need or can you use any programing skills with FPS?"
Need? No. Can you use? Absolutely.
FPSCX10 has it's own built-in scripting language.
