Was there a relationship between the thump in the front wheel and the bottom bracket observation?

As it seems more than one aspect is out of wack, recommend not attempting any repair on the bottom bracket, but instead holding off until you can hook up with someone who has the proper tools (threading tools, facing tools, etc., basically the Campy toolkit or equivalent) and knows what he is doing with them. Without a picture...I would say at best your friend is about an inch away from needing to go shopping for a frame again so best to put that last inch in the hands of someone with tools and experience.

Suggest also looking around for any solutions that avoid the damaged threads....I remember someone mentioning Velo Orange guys website for repair kits that sleeve in or press in to a damaged one.
