How can you be sure that you need these extensions if you do not completely understand them? They are a little outdated anyway, on modern hardware, most people would use vertex/fragment programs instead.

Here, try these:

In particular, try the GL_Bump demo, it covers most of the combiner concepts. There are other combiner demos there too, but I forget which ones.
