AOE boosting with prot pally for dummies ?

[Ualaa]

The only thing you need for the RAF bonus is:

a) to be linked to another account which is within 4 levels of you; and
b) for both you and the linked account to be 59th or lower; and
c) for the mobs to not be grey for either account.

If you are account B, in this chain (A -- B -- C), and A is level 80, but you and C are both level 20, and facing level 18 mobs, you get RAF.

put 3 points in improved devotion aura, this way you get a +6% healing effect when using ANY aura - so you can then use retribution aura
put 2 points in pursuit of justice so you can run faster
get a few of these shields and wack titansteel spikes on them http://www.wowdb.com/item.aspx?id=25828

is pursuit of justice with 2 points more on foot speed than a speed enchant or same (what about 1 pt) ?

I'd go with 2 and put +stam on your boots, you can really notice the difference in speed - I'm not sure that putting 1 in the talent and then having a speed enchant will stack.
edit : just checked - no stacking. Plus you get 50% reduction in disarm.

Top tip I got from a thread here a long time ago: When pulling the instance don't run, strafe instead, this way your shield will block attacks from behind and the mobs will also get struck with the poison spores from the shield . It's the best aoe tanking shield I've seen, this method works well in SM.

having unlinked booster obviously works too but you don't need to as long as there is someone else in the party for which the linked too can get raf bonus from

ah yes. I didn't chain mine so unlinked was the only way to go.
