I think you have plenty of time. There is not too much story after the 2.0 story dungeons. Most of it is a few fetch quests and busy work.

Accessories are another issue. You want to aim for what benefits your class, not just wait has the highest ilvl. Once you get through the 2.0 story, you can start collecting tomestones that you can use on upgrading your gear. This also preps you for the i90 ilvl requirement for the 2.55 dungeons and trials.

Enjoy the story and I hope all goes well for you!!
