Dang dude, that sucks. At least it sounds like you're covered with transportation until you get the truck fixed.

I can't answer your first question, but I can help out with the second. When you overheat an engine to the point of blowing it, you can usually expect to see some damage in the head. Best case scenario (behind nothing being wrong with the head) is a blown head gasket. Second to that would be a warped head which can be machined flat again. Worst case scenario, and what has happened to me twice now, is a cracked head.

Good luck, bro.
