There seems to be a lot of incorrect information on this thread. I can promise you there is nothing worse than someone coming into a shop demanding something because they got bad advice from the internet. You look silly and you lose all credibility with the shop.
It sounds like you are describing a wander to the right. This is common when caster is too low. Roads are crowned to the right (in most cases) and low caster will allow you to go the way the road crowns.
The first step in the process if you had tires put on at the time of the alignment is to cross rotate. This is to eliminate tire conicity. Read all about it here -
conicity
If you still get the pull then you have to look back at caster. Caster can cause pull with 1 degree difference left to right or it can cause wander when it is too low. In your case, you are at the bottom end of the spec. This is where most dealers and bad shops will get you. Their response is that it is in spec, so sorry. The reality is the specs are very broad and not necessarily tuned toward your needs. It is kind of a one size fits all approach.
In your case, you most likely need higher caster. In alignments everything is a compromise. You give up something to get something. To get better tracking with higher caster, you give up lighter steering and you increase steering parts wear (ball joints, tie rods, rack, etc.).
As for camber. Don't worry about it. Camber won't cause pull unless it is severely, and I mean severely out.
Toe is what causes tire wear. Nothing else and nothing more. The idea behind toe being slightly positive on a rwd car is that when you are driving, it will open up and should go to zero.
Since toe is what causes tire wear, that is what most mechanics will focus on. That is the most common adjustment because people can't feel the changes and the only obvious indicator of an alignment problem is tire wear. That is why Blackworks is right when he says that he does mostly toe sets. It isn't that he can't adjust these parts, he is following the company policy. They don't want to get involved with shims or after market ball joints, etc. Dealerships have evolved into parts replacers and not mechanics. I am sure there are a lot of techs that would like to fix instead of replace, but it is a business.
It looks like you adjusted camber on your own. That is a mistake. You can't eyball adjustments. You need to take it back and put it on a rack to get it checked out. When you change camber, you change toe. Everything is connected. That is what makes real alignments tedious and time consuming.
