Here's a slight upgrade of the tanking model previously proposed...
Protection Paladin Advised Gear:
This set is combined with the idea to reach 100% Miss/Dodge/Parry/Block chance against lvl73 mobs while Holy Shield is up. The weapon is the major source of spelldamage, accented a little with enchants and gems. All other itemization went into getting as much stamina as possible.
I went for the green-quality jewels. They are practically free, so nothing goes to waste if you later on replace these by higher-quality jewels. Feel free to replace them by their blue-quality equivalents.
