You want at least 8 in pally to get the self heal. I go to 10 for the extra taunt.
You need to spam Call to Entrench every time it's available. Sergeant's Order actually pulls things to you -- like the Marauder pull from Warhammer -- which makes it a great tool for pulling. I will ussually SO a mob, hit another with Pin Target, and if need be, use Cracking Skulls or Shield Throw to aggro any mobs that don't want to follow my plan :)
