To be honest, you probably won't have too much to catch up on besides getting access to all the Runic Portals for ToAU areas and the Cavernous Maws for WoTG which is just a lot of running around.
All the new job quests are easy, the first 10 or so missions in ToAU are cut scenes and the same for WoTG. Besieged and campaign you just have to show-up, whack at stuff and get free exp/limit points.
Merit parties and exp parties after ~55 are in ToAU areas for the most part, but everything else is still pretty much the same. Sky is crowded as ever (90 people up there last night >.>), Sea's busy, ground kings hasn't changed since the dawn of time, etc.

The number one way to get a RDM to do your bidding/NM soloing is to say these magic words: "I bet you can't"
