1. They go counter-clockwise.
2. I had a hard time figuring out the maps, so I re-drew them. Actually, I use MapTool, so I end up re-drawing just about every map anyway.

For these sorts of questions, I found rlucci's 3D map of the tower very helpful. It may not be absolutely identical to the original maps, but it's very close.
