Thanks! It looks like I'll have to set motions up, and then check all the dials in the curve editor to keep things in place. I wish there was a way to define linear as the default method instead of the curved splines. Three dials for each body part to check gets pretty numerous. I tried the quaternion interpolation, but it looked like that broke each frame into a seperate keyframe, and I wasn't getting smooth motions in-between. Render, tweak, re-render, tweak, re-render, tweak, etc etc etc...
