How many heals should I stock up on before going into stuff?
How do I decide who to pair with who?
You don't really have to worry about it too much. You'll eventually find staves and stuff laying around. But maybe buy two extra juuuust in case.
As for pairing, that's up to you and your needs.
Check out her support list and see who you want her to support with.
Or if you find she needs defense, make Frederick pair with her to give her a +4ish defense boost so you won't be as scared of people one-shotting her early in the game if you're using her to heal. That way, you can also leave Frederick as the main unit and only switch to her after moving a far distance if someone further away needs to be healed.
You can also make her pair with a mage to give them a magic power boost.
