To be honest:

Get all of the Myth Jewelery, it all has crit on it!
Get the Myth Belt, it has crit on it!
Get your AF2 Chest and Legs, it has lots of VIT/MND/PIE and they have crit on it!

Don't bother with AF2 gloves/boots, get the Allagan ones from Coil, they have crit on it! (You have done this already. Sadly they have yet to drop for me >.<)
