Good questions
The wheels need to stand vertical when pointed straight ahead, and with the full weight on them. And IIRC this will be with the adjusters in about the middle of their swing. Unless you installed Problem-Solver UCA bushings.
After that, both wheels need to be pointing straight ahead, simultaneously. Then you can crank the tie-rod adjusters to put a lil toe-in into the front of the tires. That should get you to the Aignment shop.
If the wheels are not equally vertical, a camber pull will be the result.
If the toe-in isn't close, it will wander a bit.
Unequal casters will create a minor pull in straight ahead driving and high-speed instability. None of these matter much at low-speed, going to the shop, except the camber
