Great info, Kyria, especially #19, I really wish I had known that before doing the radio station mission. I also need to figure out how to roll on the PS3, I did it once before by accident and haven't been able to do it again. This forum needs an upvote/downvote system so really helpful threads like this get more visibility.
Try double tapping the crouch button. That's how you do it on the Xbox.
