Make sure the discs are held tight with the wheel nuts and measure the gap at the front of the disc from one side to the other,then measure the same from the rear face of the disc.
When both distances are the same it should give parallel tracking.
As for the camber place something under the lower arms to load the suspension and use a level on the round part of the hub with the hex in the middle to see if it is going in or out in the vertical plane.
Negative/the top in is what you need,the width of the bubble is probably a good start.
Hope it makes some sense
