As some may said already, first do the quest for inn rooms, catch up on main story quest, make an alliance, level up your favorite class to 50 and the sub classes that the respective job needs, check point allotment as it is now, if you didnt play at all you might have the option to customize from 0, do the low level ifrit quest, unlock toto rak, so you can farm gear for your level.

Get your mounts, the easiest is the gobbue and its limited, so get asap, you can find the guy in camp bloodshore in a tent, get your chocobo too, but to be honest theres too much stuff to do that you'll have a lot to do until 2.0 release.
