i cant really help you with the parts but the rebuild is super easy as far as a motor rebuild goes. Look up a vid on you tube (most nitros are the same just slightly different so the process is the same across the board). It takes less than 20 minutes even for a total newby. Just make sure you have a good light and a clean place to work. I would recommend going over the carb with a fine tooth comb and if it looks wrong or too dirty to clean then replace it as a bad carb will piss you off. When you say suspension parts that aren't shocks, are you talking about shock towers? Shocks pretty much are the suspension so i'm kinda confused about that question.
