Exorcism and Holy Shock are just not built to be primary dps abilities like Shadowbolt, Fireball, etc. You're going to have to melee along with that to put out any kind of sustained dps.
This means one of two things:
1) You'd be some kind of gimped Ret style paladin with SP gear, or...
2) You'd be a melee/caster dps-ing healer.
That's the way I see it at least, which doesn't sound very promising.

This.
As far as I know, Exorcism, Judgment, and Holy Shock are the only 3 magical attacks a paladin gets (excluding Hammer of Wrath). Going into the Ret Tree would give you melee attacks, but they would likely suck unless you're decked out in the usual Melee DPS gear, and going into the Prot Tree would give more physical attacks, but they are pretty deep in the tree.
Even with the 3.1 change to Exorcism (they, in no way, mentioned any change to Holy Shock, so I am led to believe that it remains Undead/Demon only), it still doesn't give you enough spells to rely upon them for DPS.
