How to open eyes and mouth

I have modeled a character with it’s eyes closed and mouth closed.
But I want to be able to open they eyes and mouth to see both eye balls and teeth (inner mouth.)
Could someone please explain to me the technique I need to be able to open the eye lids and mouth.
How do I create that opening in my zbrush sculpture.

Also is there a way in Zbrush to create the blend shapes and have them transition from eyes open / close so I can continue sculpting while scrubbing the timeline to see the transition.

BTW I am familiar with Maya and I do have GoZ working.
