Looks like a good deal from what I can see. If your going for a full blown PT car, you've got all the original parts and that helps a lot. First thing you need to buy is jack stands...don't be a redneck!
Bump is just a way of keeping your post on top of the list. A lot of guys (like me) hit the new posts button and a bump will keep it there. As long as your posting in the thread it will stay on top. Usually guys who are selling do this when there has been little activity in the thread. I don't think you need to use it or should worry about it.
