Questions on Paladin Leveling: 20-30

So I just got Consecration on my Paladin, and Holy Light! That makes questing/leveling soooo much easier! So what is recommended from here? Here's what I'm thinking currently:
Spells:
Gear:
Macros:
I have most of my combat buffs macroed to start combat. that's one less key I have to click to get the killing started.
The Plan:
Wade into groups of mobs and not die. The second part is important!
Talents:
I'm thinking of working down the Retribution tree to get Seal of Command. I'm an engineer, so stunning people in PvP with bombs is a great way to get that double damage from Judging SoC!
On a side note, Consecration says it's supposed to do 64 damage over 8 seconds. I'm seeing it tick for 19 or 20 damage every second. Is this a bug or working as intended? I'm not a math wizard, but 8 * 20 != 64...
Thanks in advance!
