Question about the laser bump steer method. How do you account for the fact that even with absolutely zero bumpsteer, the dot will still move side to side because of the fact that the upright / hub moves in an arc?

Concerning the ride height at which to set bump steer - I would personally minimize it at ride height since this is where it will bite you the hardest. The big reason for setting bump steer is to keep the car from darting around while driving in a straight line. Obviously you also want the wheels to do what you intend when turn the wheel and subject the chassis to a roll angle; this is the other big reason for doing it. With any half way decent suspension design you should be able to get the bump steer minimized enough that it doesn't matter what ride height you choose, just make sure it's good throughout the whole range.
