Is this a good mass routine or am I overtraing or not doing enough? What is a good rest period between these exercises? Is 2 to 3 minutes good or is that to much?

Too many sets if you ask me!!!!!!!

2 minutes is fine only use 3 minutes on stuff like bench presses (4 for squats and 5 for deadlifts that assuming you go to failure of course) in my opinion too many sets also. Back/bis/forearms appears to be far too big of a workout to me.
