Well, I ended up going with a conservative strategy. I put Monroe Sensa-Trac shocks in the back. Two tires were nearly new, so I bought two matching ones. I also did an alighment on it. Overall, it is a pretty big improvement, the car sits on the road much nicer now.
I have no doubt that upgrading to SVT stuff would give an even bigger handling boost, but for now, get it close to what it was originally is pretty good.
Thanks for all the help.
