Look for the GMPP sway bar kit, you'll get front and rear sway bar and one strut tower brace for what the other front bar cost's almist alone ($135.00).... I used GM Parts Direct: Your direct source for Genuine GM Parts but be forewarned, they took forever to ship (3 weeks) so if in a hurry not a good choice but great price. Energy suspension Poly bushings can be had at reasonable prices and stiffen things a bit and i think the rear trailing arms make a world if difference too, I got mine from HT Motorsports for $110 shipped for the pair which is good price for solid units w/greasable Poly bushings as well.

I might be interested in a group buy, just depends...

Don't be discouraged so easily here, you said you know nothing with the car and is why you've come, some things that work on one car, might not work on another, especially considering the GP is a GM and not a Subaru and when comparing suspensions and braking between the two is like comparing apples n oranges... Totally different dynamics! . I've learned plenty about these GP's in the short time I'm here...

Anyways... Welcome aboard!
