Terrain and Sprite Help

Need some links to some tutorials. My google-fu has let me down.

I have some cliffs that I want to add realistic "lumpiness" to. How do you do that?

I also have teleporter that I want to add a plasma effect to. Need a tut for that as well.

First attachment is the current teleporter. I am redoing another persons map (an HL2 to TF2 conversion) and they have a flame sprite in the teleporter. The animation works on a listen server, but when I place this map on a dedicated server, no animation. I would like to know why that is. I also would like to use something better than that flame animation for the teleporter.

I managed to muddle through making my cliffs. That's the second attachment. I didn't follow your tutorial... didn't follow up on my original post until just now. I am pleased with how they came out. I inherited just straight brushes with granite texture from the previous mapper.
