You'll need springs or coilovers first, @
DarrenDriven can help with that
As for camber there is no factory adjustment at all, you'll need bolts (or coilovers) up front and a lower control arm (simple solution) in the rear. I'll let other folks chime in on the visual aspects.
Lowering the car can lead to the dealer denying warranty coverage on axles, but that is because lowering puts extra stress on the CV joints.
