Thanks! Tell me about it, for me it was a really frustrating process until I started getting something decent out of it. The Move-Brush is your friend! And when you get into DynaMesh a lot of things get easier =)). In case you need some online references:

The RedBeard tutorials cost a few $$ but they are really good. I have 2 of them.
oh, I'm surprised with your unexpected kindness, thank you so much for the information!
I'll try some of them and hope I can show what comes out later on :D
