Have a trusted, experience luthier of your choosing (perhaps on a recommendation of a guitar playing friend) look the guitar over. Do NOT assume that this can be done by yourself. I have some knowledge of how guitars are supposed to work, and what to look for, and I am continually surprised at what my luthier friends find, in areas that I had never even thought to look at. Luthiers, at least good ones, see more guitars with more problems in a month that players will see in a lifetime. As I said before, find a good luthier, let him do his thing, and pay him for his time.
