I'm in the process of creating full 130 sets + 130 weapon tokens and 270 sets. Those are probably enough. Also let leve allowances build up to 100 and accumulate enough rested experience before launch.

If you want a nice glamour weapon for both jobs you can save +90/+90 Aetherpool and buy Padjali weapons. By leveling in PotD you'll have enough Aetherpool to upgrade the weapons by the time you reach level 60, in the case you prefer Kinna weapons.

If you are planning to get more Anima weapons at some point, you can hit two birds with one stone by farming fates with the new jobs. Just pick up the quest and you'll get Luminous Crystals.
