Jim, I do my own alignments and I have the car set on turnplates which sit on the scales so that I can play with the corner weights as I change the alignment settings. I have found that larger changes in camber, especially in the rear, can cause weight-jacking and will definitely change the corner weights.
If that is not an option, I would get the alignment close, set the corner-weights, and then check the alignment again.
For my Carrera, I ran -2.25 in the front and -3.25 in the back. I could never get enough camber in the front due to PCA rules, or I would have set that around -3.25 as well. You could probably run around -3 because your car is lighter than mine was, and you are running the same T-bars. I would also suggest 0 toe in the front and -1/8" overall toe-in in the back.
