The biggest "roadblocks" are the dungeons/trials - either the wait times if you're not running a tank/healer or making sure you're at the required iLevel to queue for them in the first place. The rest of it is mostly just running from point A to point B and maybe beating up a mob or three.
Oh, and the cutscenes, especially the last ones which extend into hours. If you're pressed for time, it might be better to skip them and then view them at your leisure from an inn room where you can settle down for the story.
