This thread is older than time itself, but in its first post it will tell you everything you need to know about raising fame and low level gear. http://ffxi.allakhazam.com/forum.html?forum=250&mid=1151013031156001742
As for high level gear, it's mostly AF3, relic and relic +2, avatar -perp magian staves, and a few other bits and pieces like evoker's ring, sacrifice torque, fervor ring, etc. Basically anything that enhances perp, blood pact delay, smn skill, avatar/pet attack, accuracy, magic attack, or magic accuracy. General consensus is that acc>att (most of the time) and matt>macc (again, most of the time).
