I can verify that you have to follow the main storyline in order to get access to airship travel. There is no way to get to Limsa before you get the airship pass either, unless you start out there. I've read that you also cannot leave there until you get the airship pass. The ferry attendant just states the ferry "is out of service" before that part of the story. After, the fee is 200 gil to go to Limsa. I completed that part of the story today with my level 16 Gladiator.
I don't know about the dungeons yet. The servers are still too unstable for me to trust them on a longer instance.
Money is certainly not an issue in this game if you follow the storyline, and almost all of those can be boxed.
