Well I've made my own healing build and made a guide for my members, decided there's no reason to be greedy, so here it is Also the movie I'll add is of the first warfront I could record, just ment to show how it's played. I'm still new to it myself, so mistakes are likely to be spotted.

Random movie of the spec in play: http://www.youtube.com/watch?v=8n9WHpHSmK0
This build is setup for all sort of utility, having both cd's to share, extremly mana friendly, and probably the best AOE healing option you can get.
Abilities worth noticing: serendipity, Healer's haste, Life's return, Empowering light, Touch the Light, Healer's covenant, and DoL.
The build grants you 15% more armor and 15% more damage reduction in general from talents, also which makes you extremly tough to get down for melees is the 3/3 devout deflection which at rank 8 gives you a 45% ish dodge/parry rating.
From 1 macro you can get all the convictions you need both from range and melee:
cast Bolt of Radiance
cast Strike of Judgment
cast Life's Vengeance
cast Light Bolt
For a instant cast single target heal you got:
#show Touch the Light
cast Touch the Light
cast Healing Invocation
For a "OH ****" 5man heal you got:
#show Divine Call
cast Tidal Surge
cast Divine Call
For mana regain you got:
cast even justice
While you want to be gaining convictions and focusing around healing with DoL and Healing inovocation with serendipity procced, you also have Healing communion when the AOE just keeps on coming and you can't afford to build convictions. And if needed after spammin DoL you can use your healer's haste to cast 4 instant healing communion thanks to serendipity.
