does anyone of you know a good tutorial about how to use T&L? I know, that if i use some gl functions like MultMatrix i do use T&L. I also know, that there is no extension or other mechanism i have to use to activate T&L.
However i really don´t know, what i can improve my programs with T&L and how exactly i do this. So i would like to know which functions are hardware-accelerated and how i can use them as efficiently as possible.

No, those functions are not using hw T&L.
Only the transformations for every vertex itself are done in hardware (AFAIK)
With glMult/LoadMatrix (and implicit with glRotatef, glTranslatef, etc) you’re only giving the GPU a matrix that should be used for those transformations.
