Hi,
I guess the one thing I can think of is that you should make sure that the facial features (spheres) are the children of the head. After that, just make sure you select the head using branch mode ( middle mouse button, i think) when you do that, you will be able to rotate and everything will follow in place where it should. Everything will appear highlighted but if you put a keyframe it will only be applied to the the top of the hierarchy - the head, so you don't have to worry about it putting keys where you don't want to. I hope everything I wrote is clear. Try that and see if it works...
Hope that can be of some help...
