I know what you mean. Usually I grind EVERYONE up until level 40 in preperation for Desert Palace and make sure everyone has their basic abilities mastered and try to have Dagger learn most of her summons.
Having Quina learn level 5 death by eating a whale zombie (you can find them on the beach of the lost contintinent) allows you to take down those Grand Dragons that loiter around outside Daguerro or the mountains above Gizmaluke's Grotto for 12'000 EXP and 3 AP a pop. It's a great way to save time if you want to beef them up. (Not so much for mastering abilities mind you but it's a start)
If you know how you can have her learn Curaga before you're even halfway through Disc 3
