Full Break is probably the most useful 5* ability in the game right now. It's basically essential for tough fights, do it and get it to R2 ASAP, you won't regret it.
Major Black Orbs are useful for meteor, but R3 -ja spells might take priority.
Nah. I don't bring any sort of breaks for ultimates unless it's required for medals.
