Check out AutoAnything.com (that's where I got my fronts, rears came from TR because AutoAnything didn't have them in stock). When I got mine they had a 20% off coupon for new customers, and while I can't find that right now, I didn't find a 12% off coupon that works: EAP129WS (expires 4-13-12).
But with the coupon it comes to $538.38 shipped (free shipping).
You are correct FSD's are not designed for lowered cars and the Sports (yellows) will work much better. On the sports damping is internally adjustable on the rears (meaning you have to compress the shock fully and spin the rod to adjust the damping level, this can only be done with them off the car) and externally adjustable on the fronts (meaning it can be adjusted with a knob on the top of the shock).
I personally haven't adjusted mine since I installed them.
