I think most of your questions about pipework could be solved by spending a while tracing the pipes so see what they join and where the seacocks/taps are. Doing it that way will give you far more information (and understanding) about your boat than you'll get from any forum. Much of the plumbing may have been changed from the original spec during the life of the boat so forum answers are going to be "best guesses" in any case.
