two n00b questions: What is Camber and offset?

camber:
A wheel alignment adjustment of the inward or outward tilt on the top of the wheel when viewed from the front of the vehicle. Tipping the top of the wheel center line outward produces positive camber. Tipping the wheel center line inward at the top produces negative camber. When the camber is positive, the tops of the tires are further apart than the bottom.

offset
The distance between the centerline of the rim and the attachment face of the wheel disc at the wheel hub.
