It would be very easy to just sister rib the broken area and install new cap strip.
If you are going for full rib removal, the hysol will normally come right off with heat and a scrap piece of wood.
Best documentation is pictures, pictures, pictures. You don't have to have a written description of every step, but a good over all written log. IE, you dont have to document every bolt that you turned, but you can just state that the "elevators were assembled per the written factory instruction" etc.
When I rebuilt mine, I noted that "wing rib tails were replaced per factory instructions" (along with many more entries such as that for various parts of the rebuild) and the FAA inspector did not have any issues with it at all. He spent about 20 minutes going over the book, 10 minutes on the plane and told me to have a nice day and enjoy flying it!
