@Travis, I used a Weber chimney full of KBB, spread evenly on the grate.
Put the pan on and went to town.
It was finishing up as the coals were dying out, so it was like turning the heat down to simmer. It worked out well.
@Jason, I think paella is a personal thing. Put whatever you want in/on it. My wife isn't a real big seafood fan, so we probably won't have anything more exotic than maybe some breaded shrimp thrown on top for variety.
