200 bucks seems like a steal! I just went through the rebuild process, it's fun haha! 560 is a pretty big bore! idk if Wiseco makes a piston that big for a 500??? so you might just want to get a brand new top end with a fresh sleeve there would be less heating issues that way. I myself would replace the rod and bearing because these bikes have a bad history with those. As for the crank I had mine welded...but I'm sure there are some guys that'll say it is not needed. For the frame if I were you I'd find someone to repair before the powder coat and just play it safe. Good luck on your build man!!!
