What are the appropriate frames to use around glass for my test chambers? I found some models for frames, but I'm not entirely sure if they're the ones I want or not, considering they have preset sizes, and my glass is too short and too long for some of them.

You can make custom frames out of brushwork (which is what most people did in portal 1). Just remember to func_detail it.

Ah, okay. What texture(s) would you suggest I use, though? I'm really not sure what to use, myself...

I think most people stick to plastic/plasticwall004a
