You make a good point about the unequal length and it so happens that the front springs required very little preload to get to ride height. I was thinking that the heaver springs should be on the rear instead of the front when I was setting ride height. I have the 275 in the rear and 350 up front with the yellow shocks.
You can't measure the alignment with the car being supported under the ball joint on the lower control arm. By doing that you have effectively reduced the motion ratio of the front suspension which will result in a higher overall ride height. The best way to do this is to put the tires on and set them down on slip plates. You can buy bearing style slip plates or you can use a couple 12" tiles with grease between them so the tiles slip on each other.
