As long as you're not trying to beat the final coil, any setup is fine. The ultimate thing you want to improve is your weapon, as Weapon Damage outweighs every single stat in the game. You can be a very decent SCH with 30points in INT (remember, for healers, skill > gear), as well as a good SMN with 30points in MND.
If you cant choose, go for MND, it will increase your DPS in SCH in Cleric Stance.
