Even more useful replies! AWESOME! This'll definitely be a huge help as I learn and experiment. :]

  Reading them has brought forth another question...

 Someone mentioned Inverse Kinematics. I was under the impression that IK is bad except in rare situations? Every time I've bought a product the instructions told me to turn IK off...

 I just tried using IK on the arms in an animation I was working on.. in the middle of it.. and it worked fine. But then I turned it off.. and it screwed up the characters hands, from frame 1! Everything was messed up!
