So I hit level 60 as a White Mage...

Had to re-read the first post because well.. I'm really not understanding why people are even entertaining the idea that you grind 260 gear.
Screw that. It's absolutely unnecessary and a waste of time. Even more so from the fact you're playing the most gear independent class in the entire game (whm).
Finish up your msq to 70, grab some vendor, dungeon, and/or quest gear along the way. And that's it.
Do side quest at your leisure (I know some people love doing them) but certainly don't force yourself into grinding anything at 60, be it quests or gear. The only mandatory grind right now will be the MSQ. If you even consider that a grind.

My one suggestion would be not to insist too much on your lvl60+ class quests if they're too hard. Just do them when you hit 70. Also, lvl 60+ dungeons hit hard so keep your tank topped off during progression.
