If anyone's interested in getting maps of their world, I found a really great tool called MCMap Live. This one's for the Mac, but there is a Windows Port. With most Minecraft map tools like MCMap, you don't get to see anything until the render, which can be slow and boring, but this tool uses the MCMap engine and renders it in realtime, allowing you to explore, zoom in and out and peel layers back. It's also fun to use.
