Agreed, do a total tear down and you can get to know your truck inside out- therefore you can fix and pinpoint pretty much any problem.I would suggest tearing it down and cleaning it since no one mentioned that earlier.
Seriously, the best thing you can do is get completely familiar with how everything fits and works by giving the entire truck a complete going over. That way, when you DO start it and run it, you'll have a thorough knowledge of what's going on with it.
