Nothing Better than a good leveling build for a Cleric. My favorite is the Shaman they do good damage and are tough as nails. This is the Level 35 version of my Build along with Macros and a video of the one button Spam working on an Equal level mob.
This build is pretty simple. I go as much as I can go into Shaman for Single Target Damage and the rest into Purifier for healing and shielding. Justicar is just for the passive buff Salvation.
At Level 35 I get about 300 DPS fighting an equal level Mob and finish it quickly with a full health bar. The Macro has one shield built in and I keep another on hand to put up when that one falls. The shield absorbs about 40 DPS and your passive heals give you another 40 HPS. I rarely even use my heal macro.
