For your fist question... You can assign seperate FX files to anything you want to.

For example; By using the d3d_automaterial var, and by creating materials that are named as your textures in the WED texture manager, you can have control over them.

Code:

WAD Tex name               Material name
lamppost_tex               lamppost_tex 
stonewall_tex              stonewall_tex
tabooidol_tex              tabooidol_tex
etc, etc


** I put a tutorial in the WIKI for doing the level geo. It is in the Titorial section under Effects.
