It'll ride fine. Probably much like stock, a bit more firm and sporty in the corners.
Stock shocks would be fine, I rode on my stock shocks with H&R sports for 2 years, no problems.
But if you have the money for high quality replacement shocks, I'd get new shocks at the same time.
With a drop that low, you won't have to worry about camber correction. I have uncorrected negative camber, but I just rotate my tires, no problems after 2+ years. It'll be within the specs up front, and perhaps just slightly out of spec in the rear, but nothing to worry about.
Talk to v6master on this board. He has a nice 2002 V6 sedan with the comptech springs and Tokico Illumina shocks and says he's really satisfied with the setup. I've seen his car, looks great. It's not a real noticable drop, but better than stock.
