Optional Talents are Cleansing Waters, Ancestral Resolve, Acuity, Ancestral Awakening ...
There is a build going for Telluric Currents and/or Focused Insight with Elemental Precision, giving up instant ghost wolf instead.
Resto builds heavily depend on your raid format (5, 10, 25) and your role as a healer (tank, raid).
Riptide, Earth Shield, Earthliving Weapon. Water Shield is an option if you have terrible mana problems.
By preference/encounter/raid setup any of Healing Wave, Ghost Wolf, Healing Stream Totem, Chain Heal, Stoneclaw Totem, Hex
Intellect > Spirit > some order of Haste, Mastery, Crit
The debate on the best secondary stat (after Spirit) is always controversial. Haste is a very good throughput stat that comes with an increased mana requirement. Mastery increases heals when targets are low which is certainly helpful. Crit is both a throughput and a (weak) mana reg stat and effects everything (unlike haste/mastery).
Basic Priority List:
Not really a priority list. Main advice for new Shaman healers would be to keep the shields up (Earth Shield, Water Shield). Try to always have the Tidal Waves buff up before casting a direct heal. Healing Surge is pretty bad now and should only be used in the most dire circumstances.
