What's "right" can be different for everybody.
You've got to get the front high enough to not rub the tires when two-up, but not high enough to look too high.
You've got to get the rear to sit not too high(into positive camber) or too low(bottoming out). I initially ran my Spyder pretty low all around, but raised it after I bottomed on speed bumps going into Lime Rock Park.
I have the rear set around 2.5 to 3.5 degrees negative camber(depending on weight in the seats), and the front to be level with the rear height or slightly lower. Slight front-lower rake helps high speed handling(110+). The front is about 1.5 degrees negative camber.
I run 1/16" toe-in, both front and rear. These settings have served me well over the years on the street, Auto-X, and DE laps.
