I don't know of any, and just did a search on "stability ball CD" with no luck.
I would think that what might work best in your situation is to find a personal trainer for a session or two, who could show you exactly what to do (actually feeling the placement of the ball, etc. in your body will help you remember it when you workout on your own. ).
Or maybe even a friend who could come over and guide you through a workout on video or DVD?
There are several stability ball (swiss ball, balance ball, it goes by different names) book available. Maybe some are available in large type (if you are just "legally blind" ) or braille? Or maybe even as books on cassette?
