The best thing to do is to reference those files in a new sprint rom. I copied most of those files into the OEM so I could easily identify them and remove sprint's customizations as the new rom's come out or if I needed to start clean again...So yeah, they might be a little old. It was just an easy way for me to remember.
UCAutorun is one from the ppckitchen that I think old_man_jenkins fixed and I further modified, and the other two folders are ones that come with the stock rom.
