Well, because my front sway bar decided to break off at the end, I decided to skip with a stock replacement, and get the GM Performance Parts handling kit. It was only a $45 difference ($130 v $175) so I went with it. I got the kit a week ago today, but I had to wait until last night to put it on (open shop night).
Here's the GMPP handling kit.

Hmmmmmmm......

Old bar next to the new GMPP front bar.

This picture shows how much beefier the end is on the GMPP sway bar.

All the old stuff I took off.

I didn't take pictures of the trailing arm/rear swaybar install because it installed so fast (I had my roommate helping me at this point) and by the time I remembered the wheels were back on and the car was on the ground.
As far as the feel goes, I really haven't had a chance to corner hard yet. It's a pretty lame drive back and forth to work, and that's all I've driven so far. lol
