If you can't get everything you need by trading or purchasing through members of the board, the first place you should head to is
here. Bob's got really competative prices. I ordered everything I could from him first then went down the list and ordered from other places. The only thing I've found cheaper is Peale has really good prices on wire, disconnects and locks. I can't seem to access his parts page right now, but drop him a line and he'll be happy to help ya. Good luck on completing your list.
