The car still handles miraculously, and even better. But, I would love to regain a little steering feel. Do the positive steering response bushings that add caster help with this once larger tires are introduced? I assume the larger tires are the cause. I have camber bolts for the front that the allignment shop didn't install because I had zero camber (I'm unhappy about that), and I am going to put SPC control arms on the back to reduce the -2.1 degrees I have back there. I want to get to around -1 front and rear if possible. Do you reccomend these camber settings for a DD/weekend ringer/occasional autocross car? Would some negative camber help with the soft/vague-ness of the steering? Should i do the positive steering response bushings such as those offered by Perrin and Whiteline. Please advise, and thanks for this thread!

The alignment alone will have a pretty big effect. Get as much as you can with the bolts up front...you'll still have well under -2 so don't worry about tire wear as long as toe is 0 or minimal. -1.5 would be nice if you can get it. For the rear, -1.5 or a little more would be good too. This is assuming you're running decent tires.
The bushings will definitely help too and we feel a big difference with front control arm bushings like the PSRS kit and the Whiteline ALK. The extra caster is nice as a bonus.
