1. I have an old wallet saved (unencrypted) with a few coins on it. I took this off my old computer and just downloaded the bitcoin client again. Is there a guide to plugging those coins into my new client? I figure there is a guide around somewhere, but though I could ask.

2. More pressing and difficult.. I used to use Bitcoin OTC way before you needed to do some sort of PGP Authentication to even join the channel. In general, I had problems using Win GPG or whatever it was called, so there are probably keys from a few attempts sitting around on my old computer. I need to figure out what I am looking for and how to join OTC again. What am I looking for and how do I do this?
