Help moving a section of animation

I am hoping somebody here can offer up a quick and clean way to go about this. Here's the situation: I had my character doing a parkour scene, but it was all in a straight line. I have changed it so that half way though the scene, he takes a left turn and the animation continues just like before, except now he is around the corner. My problem is that I cannot relocate the second half of the animation easily.
Things I have tried:

--  grabbing the hips, hands and feet and moving them all. This works for translate but I can't rotate them together, they just rotate on their spot, destroying the pose.
--  parenting the hips, hands and feet under a null group, then moving and rotating the group. This gives the desired translation and rotation but it messes up the animation while the group is being moved.
-- making angry wookie noises

There might not be a way to accomplish this, in which case I can do it manually. I just thought I would check to see if somebody knew of a fancy trick. Thanks for reading. As a reward, in case you didn't know,  Alt + V is the hotkey to play/pause your animation instead of clicking the play button.
