As far as setups go a this is going to be why I will miss so cal so much. That place was bumpy with med traction. The really nice thing was that conditions were consistant so you were able to see how changes affected the car. At most outdoor tracks that water, the amount of water in the track will affect the traction and make changes harder to notice as the traction level is always changing. If I got a setup that worked well at so cal it worked everywhere!
In most all cases I would start with the kit setup and tweak from there. If you have to make more then 4-5 changes and the car is not getting any better, go back to the kit setup and try and different direction.
e.g. If you tried fixing the car with shock changes, oil and springs and that did not work go back to the kit setup and try camber links or roll centers.
