Great suggestions skyl4rk. I've also been asking around on a few of the Atlanta bike messenger boards what kind of rules people in the city tend to follow and they all seem to agree that you can pretty much do whatever you want, so long as your watching traffic way ahead of you (much like when your hypermiling) and that you just stay aware of your surroundings at all time. I know riding in the heart of Atlanta is a lot different then it is in my area, even as urban as it is, but the same rules should apply regardless of where you ride so keeping an eye well ahead of (and behind) you will generally keep you from getting in any situation you could avoid if you had only been watching people's driving behavior.
I've also come to agree with the curb thing, being a "death zone". I used to kind of scoot over a little and drop into the concrete part between the road and curb to sort of signal to cars that I knew they were there and that I was aware they wanted to pass, but the other day I did that and nearly clipped the curb because some jack@** apparently thought I shouldn't be on the road so he took my moving over as "o, yay more room for me", and he moved over too. When he passed he almost brushed my shoulder with his mirror...I think I'm going to start wearing a helmet cam so I can get license plate numbers on these people...
