Preparing to Camp Out in SF

Okay, so Ngan and I have decided to camp out in SF tonight to wait for the beloved Nike Air Max "One Time Only" shoes (oh yeah, and a pair of Jordans). I've never done this before, but want to be prepared. So, I'm going to pick up a few things to make this little adventure as painless as possible. Anyway, I'll post a summary of my findings/packing list, but wanted to share a possible blanket. A 2 person survival blanket -- is this overkill or what?
