What is the best way to order your spells in the task bar if you are a level 85 Human Paladin on World of Warcraft

This is currently (9/25/2010) unknown as you can not be a level 85 anything on the live servers.

On beta servers, it is best not to say what is the best way to do something because Blizzard has not finalized its damage and healing numbers, and probably will not until Cataclysm comes out.
