Here, IDK if this is what you want, but I have been working on a series of tutorials that cover EVERYTHING you need to do to create a prop and make it FPSC Ready, in my Complete FPSC to Milkshape tutorial.
I know your using Blender, but the UV Mapping and Texturing part could be useful for you. Take a look.

NOTE: The Texturing part will be uploaded tomorrow. Stay tuned for that
