Looking great.
Make sure you understand the inverse/forward kinematic workflows. Both are equaly important sadly...

Don't worry, you just have to add a few modifiers to your IK related bones so you can switch between the modes, but IK allows you things like walking and climbing without any sliding.
Well, ironically, that is exactl the thing IK is most useful for.

Oh jeez... I only rigged my character, I didn't do anything IK related.
