For the "pop" as it comes out of the socket I would sue something like a lattice to defoem the shape of the eyeball to "pop" it from the socket.
Or use something like Ncloth, make the eyeball a cloth with a preset like the beach ball and the head a passive. Parent the eye to a locator then aimatate the locator to pull out of the head. A mess about with the settings should get you to have something like what your after using dynamics.
