One thing to keep in mind, when moving from the Hip, is if Figure > IK is turned al the way on, or all the way off.

If you want to save the position you've moved youor  character to, then you use the Hip,  If you have the Hip selected, when you save a pose.pz2, then upon loading that .pz2 the new figure's Hip will be moved to where the Hip was when the .pz2 was saved.
