1. Nope

You just have to explore and learn the areas. It's pretty straightforward most of the time... The wilderness maps have roads and such. But the Laanx Dungeon you might have trouble.

3. Two, I believe. Ojaveda the enkidukai capitol and Hydlaa, the main city. There are a lot more places to explore than just those, though.
