Eric - The airfoil and hence the curvature neither the thickness of it has any bearing on the wing area for aerodynamic calculations. In other words, simply calculate the area of the polygon traced by the wing to get the wing area.
Don - MAC is a weighted average of all cord lengths on a semi-span. This is useful for simplifing aerodynamic calculations on a tapered wing. MAC is same as chord on a rectangular wing.
