I too found this thread because I finished up Nar and couldn't find my way out.
1- I play once or twice a week, I arrived in Nar 3 weeks ago!
2- I keep my game windowed, with chrome open for quick googling of quests (who doesn't). If finding info on the web saves me a minute or two, what's the big deal?
3- In general I think the flow of swtor's worlds so far has been sketchy. Part of the strength of a normal mmo is that they are usually continent based. Continents are good for mainly linear gameplay. Just look at the level ranges in wow, it's usually clear where to go and where not to go. And the map is always marked with an icon.
The spaceport thing is like if every zone in wow had portals, ships, zeppelins.
When you don't have that normal linear flow, you need to rely more on iconography than normal. They don't seem to have done that.
