Patch 2.2 Checklist:

• Main Story completion.
• Grand Company rank completion.
• Complete Ultima HM/King Mog

Some optional things people may want to consider:

• Stacking of myth/philo.
• Collecting some materia relevant to your job.

It might be a good idea to take a look at some of your armor/jewelry pieces and see which of those pieces are weaker/have less favorable stats in comparison to everything else. There's a good chance the new crafted gear might be able to replace those weaker slots.
