Great pictures! I love thunderhill -- it has a great mix of high-speed "horsepower" turns with tight, off-camber corkscrew stuff. I bet you were happy to have those upgraded brakes too!
As for the body roll: I'd recommend stiffer coilover springs, but then putting the stock swaybars back in. It'll ride about the same as it does now on the street, but will not rock & roll quite as much on the track.
PS: try not to lean your head in the turns. When I first started autocrossing & timetrialing, a local hot-shoe spotted me doing it and told me not to. I was amazed at the difference -- you just seem to be able to 'feel' the boundaries of the car so much better and wind up using all of the track instead of giving up that extra foot or two... Plus your inner-ear will be better able to detect minute changes in the car's balance.
