Most of the references I can find to original work was for MDD (okay now Boeing but for DC/MD not 707) and no sign of this Airbus chicanery you imply.
Sources please?

747FOCAL,
You are correct to say that Airbus did not design the A320 wing.
You are incorrect to say Boeing had any part in the A320 wing, that was done under the guidance of Mr Back and Mr Wedderspoon at BAe Weybridge, they did use some stuff from the Royal Aircraft Establishment....but no GDY involvement was required.
BAe Weybridge has being doing wing design for airbus going back to the A300.

mostly harmless
a question:

Does this imply that the 737NG has an inefficient wing? And if so, given that the wing was re-designed, why?

Big winglets on a short hauler are a sign of an inefficient wing to begin with!!

There are a few undesirable characteristics of the 73 NG's wing (principaly being prone to icing and hoar frosts after cold soaking), but inefficiency certainly isn't one of them.
The leap in performance between a 300 and a 700 with identical thrust ratings is huge, the fuel savings are significant, the cruise speed is much improved and the TO/app speeds are about 10kt lower.
