The fact that those two discrepancies you stated are diagonally opposite each other point toward the frame being racked. The driver side rail is sitting farther back than the passenger side relative to a perpendicular line.

Joe's suggestion to use plumb bobs and masking tape is ideal.

I'd create a virtual map of the frame with lots of points on the floor.

Take some measurements from a level floor to points on each side of the frame to see if it's twisted as well as racked.

Be glad you noticed this now before installing the bodywork. A frame shop ought to have an easy time stretching things back into shape.
