Some of it.

The Temple Boots are very very easy to get. The Temple Circlet is somewhat harder. It's technically possible to solo your way to the Temple Gaskins in U'Ghamaro mines, but is not easy and will almost certainly require the use of other L50 classes than MNK. Dzemael Darkhold is not soloable, as you need 4 to enter the instance, and 6 at least is recommended for the miniboss. The AF is in a room almost immediately after that fight.
