You may want to complete 500 delivery and 200 supply missions, as well as collect 500.000 seals and achieve pvp rank 40, if you care at all about achievements. You should at least be sure to have your battle log filled (complete rank 3) to get the achievement for the minion and buy chocobo barding and chocobo minion.
Also, win 100 Frontlines to get your pvp mount for the Adders.

Then you can start all over again with another company ^_^
