Brandish

I got a STP3 for next to nothing and I am looking at upgrading some of the components cause they are pretty much garbage. This is going to be my park bike and I wanted to build something that can take my beatings at the park everyonce in a while. I would like to swap the cranks they are pretty much the weak point of the bike, anybody have any ideas that are cost effective to replace the cranks? I don't want to dump a ton of money in this bike since I am collecting bikes likes its nobodies business. I would also like to go to a single chain ring any suggestions on a good size for park riding? Im just got into park riding so any help would be appreciated.
