Centering the steering rack and the steering wheel is a contributing factor to wandering. Bear in mind that the steering rack has a spool valve that the steering column connects to. That valve is designed to stay in the center except when making turns. When you turn, you are actually diverting hydraulic pressure from bypassing to providing assist to one side or the other. When it is operating off center, it mechanically senses you are making a turn - even though you are not - and is attempting to provide assist top the side that it is off center to. Any proper alignment includes centering the steering.
Again, looking at the numbers, 3 tenths of a degree (about a quarter of a degree) difference from one side to the other is certainly not enough to cause a pull or wander.
The SAI difference causes me more concern than any other thing. Changing the control arm will probably not correct that. I suspect that you have damage to the suspension tower that is not readily visible to the eye. That would most certainly cause the car to more readily go one way than the other. I have seen as little as 1/4 of an inch cause major problems that didn't even show up on an alignment rack. As other posters have said, I would consult a body shop. Something more radical than an alignment is wrong.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
