Feats for a caster Bard

[Angry Wizard]

I'm looking to make a caster bard that prefers to cast spells and make sweet bardic music to support his meatier allies rather than fight himself. Any particular feats that would help support this playstyle?

Spell Focus, Greater Spell Focus, Spell Specialization, Metamagic feats (Extend, Piercing, Coaxing, Quicken), Peacemaker, Charming Performance, Spell Penetration, Spell Mastery...
