First level druid? For my first level druid, I took Animal Defiance, but that's from Masters of the Wild, which may no longer be allowed.
I'd say Augment Healing. As you can't afford to prepare lots of healing spells, you can as well make them as efficient as possible. AH for a first-level caster gives you cure minor wounds at +2 hp and cure light wounds at 1d8+3 hp. Then later you could take Spontaneous Healer (if your arcane class is Bard or Wizard, you'll be able to satisfy the prerequisite without wasting skill points on cross-class skills).
Also, you can take Sudden Silent to be ready to cast spells stealthly or in area of magical silence, and then Sudden Empower. Sudden Empower is very useful, for a lot of things -- damage dealing spells, fodder conjuration spells, etc. If you're human, you can have both at first level.
