Magic damage only. Sumoners, scholars, blackmages. Ether is super useful, as above said, to simply keep on singing. Also good when the bard dies, to instantly get a good start on refilling that mana bar.

Foe is good for BLM and SMN always, WHM and SCH if they DPS, and NIN once a minute if he's using Raiton. Don't go out of your way to sing for a NIN, but if you're just standing around before a pull, there's no reason not to unless the NIN isn't going to Raiton for whatever reason.

As far as ethers, I personally preferred to keep an X-Ether on standby. An X-Ether should be enough to keep your healers afloat for a while with ballad even if you didn't have much MP before using it.
