Helaing as WHM is fine on PS. I have been doing it since Aug on PS3, and now on PS4.
When I reached lv50 (actually, arund ilv65), I did a major rehaul of my hotbars tho. I had 5 hotbars fulls of shite. Now, I only have two:
Heals - including all healing, Divine Seal, Protect, Stoneskin, SoS etc. Its my dungeon/raid hotbar
Normal - this is mostly dps and buffs (PoM etc). For when out and about on my own, and also for dungies were I can.

Key point, I have CureI and CureII are in the eact same place on both hotbars, tho - this ensures if I'm DPS and some one takes a hit I dont do a Hotbar panic, I can cure fine, and while cast is happening I can always flick back to my Heal Hotbar.

But, you will find what works best for you!

For sure, PS Healing is groovy.
