I have modified suspension so my information won't help you but you are right on the money, knowing the effect of increasing camber on toe would be very good IE one complete turn increases camber by -1 degree and requires 1/2 turn on the tie rod to correct toe. I made up a chart for both the front and rear of the car so that I can make adjustments in the field and maintain reasonable alignment settings. Changing caster will effect bump steer, ackerman and toe but it is well worth experimenting with. Changing toe at the rear will effect upright inclination which will effect bump steer also so you need to adjust the inner link fore and aft till you get correct toe with the bump steer you want. That can vary from toe out in bump (tight autox) to 0 (street/ road course) to toe in for stability (street).
