Cleric, healing is the number one priority, but then again a bard can heal, but a cleric would kick a bard's ass in combat, but if it was with any sort of sneaking or running away than the bard would be a better choice.
I would recommend a Cleric1/RogueX, with just enough Wisdom to cast 1rst level spells. You can generally take care of yourself as long as you don't get into a huge melee.
