http://www.youtube.com/watch?v=-NjOeg4oOJY here is a video that might help. It doesn't directly help you with texturing or talk through it but look the the steps and brushes he uses to make the texture look tf2-like. As for the compiling you just need to use the import system (which is smd for model and the texture needs to be tga.)

thanks

If you think you can't texture it I can give it a try. I'm getting better and not that good at modeling.
