Without buying any skills:
Healing Touch (or whatever that spell is that requires you to touch someone to heal)
Healing Breeze
Remove Hex
Mend Ailment
Reversal Of Fortune
Shielding Hands
Resurrect
Smite
Put as many points as you can into Healing, then Protection, then Smite.
This is the starters, when you don't buy any skill at all.
By the time you leave the Island, you should have enough money to buy skills, armor and weapons. Then it gets fun.
When you get to Tyria, you should be around 20th level. There, you can start to get free skills from quests in Tyria. So make sure that you buy skills that can only be found in Factions, no sense in buying something you can eventually get for free.
With Tyria and Factions at 20th level:
Orison of Healing
Word of Healing (e)
Mend Ailment
Rebirth
Vigorous Spirit
Heal Other
Healing Breeze
Healing Touch or Divine Boon or Remove Hex or Signet of Devotion
If I bring Divine Boon, then I also Bring Boon Signet and not Heal Other
Hope this helps.
