Where do I find all of the L4D models and materials so that I can port them into CSS?

I tried using GCFScape to find the file that contains all of the models and materials and extract them, but the one problem is that the only file that contains some of those files as far as I know is left 4 dead base.ncf, and that only has little to no content inside. Is there another way to find the L4D models and materials?

Steam\steamapps\common\left 4 dead\left4dead
then open pak01_dir in GCFScape.
