How do I know where I'm going in the game?

Google is your friend. That said, there is always an easy way and a hard way to get from A to B.

The easy way in this case would be to get a Druid port from Butcherblock to North Karana, and then run to South Karana. The hard way would be to take the boat from BB to Freeport, then run through East Commons, West Commons, Kithicor (high on the zone wall at night; high level undead roam the zone at night), Highhold, East Karana, North Karana, South Karana.
