You're running 20" wheels, so you don't need - or want - too much negative camber. That said, you're lowered a substantial amount, so your suspension is basically operating in the upper 1/2 or maybe even 1/3 of the design travel range. With our MacPherson strut front, what's left of your suspension articulation likely doesn't have much camber gain left. That camber gain might even reverse when nearing the extreme end of compression. If so, your front will start exhibiting camber LOSS. Not good. So... having at least some static negative camber might be a better compromise... to preserve some dynamic camber on the outside wheel.
As for the toe numbers... I prefer alignment shops that measure them in degrees, instead of raw differential distances, which is what I think your numbers are. With RWD, front toe is usually set between 0.00deg to a very slight amount, like 0.20deg. Rear toe - on the driven wheels - should have a little bit of toe-in, like less than 1/2deg total.
