For the first question, I would reccomend you go to the yahoo vega group home page and do a search of the archives. There has been a lot of previous discussions (more than the recent discussion) on what's inside the keel, where is it, what model vega do i have, keel ports, etc.
for the other questions, I'm not the best one to answer..
