Speed Academy has a great video on setting tire pressures and camber using a pyrometer:

In short, there is definitely a correlation with temperatures between tire pressures and camber settings.
Because you've already maxed out your available camber and I can already tell you that bolts alone aren't enough, you can expect the outer edge to be quite a bit hotter than the inner edge. What you are going to want to look for when setting pressures is to see your temperatures across the tire be about evenly spaced. I don't know what the real numbers will be but something like 110 inside, 120 middle, 130 outside is a good spread and indicates good pressure. If you've got something like 110 inside, 125 middle, 130 outside then you might be slightly overinflated. Alternatively, something like 110 inside, 115 middle and 130 outside might be slightly underinflated. The point is to aim for an even spread of temperatures from inside to outside. Note that depending on the camber and the tire, you may not be able to get the values completely evenly spaced so just shoot for as close as you can get.
