Looking For Cleric Build for Heroic TR'ing, Casting spec

[Kabaon]

I'm looking for a cleric build for casting, not sure what stats I should be looking for.

I'm 36 point build, I have a sup +8 tome (though it won't get past+6), will not be doing much epics except for tokens.

I'm leaning towards Aasimar and putting 20 wis, 16 cha, and 12 con (I could be horribly wrong here)

Non-Iconic.

Any help will be appreciated
