With regard to the blendshapes and modelling thats quite straight forward. Obviously its rigged and you dont want to undo anything.

Presuming you did your blendshapes befor you rigged it heres how to solve your problem:

You basically duplicate the original head and move it off to one side (DO NOT FREEZE TRANSFORMATIONS!), reshape what you need to then create a new blend shape with this time the setting in the blendshape options needs to be set to Parallel then once the shape is created go to the channel box and under Parallel Blendshape simply type value from 0 to 1 for the appropriate mesh. The Shape of the face will now change. Then right click over the Value channel and do Lock Selected. this will stop you moving the value by accident. You should now be able to do your animation or move the head without probs.

Ive been using this type of technique on characters for four years and it works absolutely fine, it even helps using this technique to create new characters from the same mesh and use old blend shapes from the original model....but that I'll save for another day
