They are quality parts. You may not need the rear camber alignment kit, just kinda depends on how your car reacts to the drop. You definately won't need one for the front.

The sways will be great, as for the shocks, I'd look at Koni, Bilstein, and Tokico Illuminas. Also I think I've seen an Eibach setup that comes with a spring shock combo on www.tirerack.com that's probably worth looking at...it would likely be cheaper than the prokit + koni's and I would assume it would perform decent.
