My honest suggestion? Go healer on your character first. You will level faster, see the game faster etc. Some tips that are useful? As WHM, be careful about when you cast Regen. Don't spam Cure II. Do your level 45 Job Quests before a certain Primal trial if you don't regularly have the best and up to date gear.
And then you will get the +50% exp and your own personal experience while you level THM/BLM. Also, you will thoroughly miss your healer queues ;p
Don't feel pressured to do one or the other. Do both! On the same character!
Keep in mind that if you choose SCH over WHM for your healing, SCH's base class Arcanist (ACN) is considered DPS until level 30 when you actually get SCH. CNJ (WHM's base) is considered healer the whole time
