I could contribute with the map for the mine cart stage *if* I can find a way to present correctly. As it stands, a full-size map with everything connected would probably be around 100,000 pixels by 100,000 pixels in size, which I'm confident no home PC could handle anytime soon.
...Seriously, the first part (up to the second switch which is all I've mapped so far) is about 21,000 pixels wide and almost just as high. Heck, I've been mapping it in sections to avoid the size issue.
