I would be interested to know what your accuracy is, and what damage modifying stats you are missing to get your accuracy. It's true that Monk has natually high accuracy WS's, but if you're under 95% then you're too low. (Aim for 100%)
Unless your accuracy is 95-100%, then accuracy>damage
Ifrits Claws + Explorer's Choker(Atk + 30, Acc +15)
Moogle Fists + HQ Electrum Choker (Atk + 30, Acc +30)
Don't forget that DPS is a damage modifier as well.
Relic>Garuda>GC(With 5 Piece Bonus)
