Sorry, don't mean to be sarcastic--If the guitar isn't worth much, it isn't worth putting any money or time into fixing it up--and if it is a good instument, at some point, you will realize that the repairs require good work instead of slap-together work--I went through this once, with an old Gibson, and in much better shape--by the time the dust had settled, I had spent quite a lot of money getting everything right--even the nut and floating bridge may be more of a problem than you may think--since they are not exactly one size fits all--
