I am planning to go this route. Yes you get some white mage spells as a Paladin. (About ten throughout your whole Paladin Career) Being a pure Paladin does not allow you to be anything but a backup Healer.
However if you use a White Mage as a subjob you will get the added magic points, regenerate magic points while not in rest, and get many many more spells then you would as a Paladin.
Paladins only get Cure, Protect, and light damage spells.
White mages get more effective versions of the above, and group healing spells, poison and parlysis removing spells, and Divine Seal which doubles the effictiveness of their next healing spells.
Paladin/Warrior is strong tank with backup healing and taunt (Which is valueable) many people will go this route.
Paladin/White Mage is a good tank with good healing. You can learn to keep agro without provoke by healing the person being attacked.
Paladin/White mage seems a much more interesting and capable class.
