there's a lot of programs like:
-3ds max5
-franco coordonaites program
-zmodeler
-resdecode;rescovert
-mabye photoshop for some textures
-txdworkshop
-rw analyze (is not ok to use it! If the model is locked, you have to ask the autor for it)
Yes! There's some tutorials, but not one big tutorial with all. I saw on GOM some little tutorials in that it is explained how work that programs. Is better to start with a rim, not a car.
Did i forget any program?
