Hello.
FeynCalc only does dimensional regularization.
If you look at http://www.feyncalc.org/FeynCalcBook/OneLoop/index.html you
will see a couple of examples. Many more will come when we finish the
documentation we're working on.
See als the thread http://www.feyncalc.org/forum/0048.html
Regarding the permutation of indices, I'm afraid you'll have to be more
specific.
