Something to remember with Battleforged vs. Dwarven armor - Dwarven lets you get one free healing surge per day (14 hp for you), whereas with Battleforged you get 1d10 extra hp every time you second wind when you're bloodied. If you save your second wind until you're bloodied as a matter of habit, then it should give you more hp over the course of the day, and help more in each fight than Dwarven (which only helps in one fight per day). Black Iron is pretty good too, gives you some resistances and is level 4.
For weapons, Terror is pretty good for a defender. Flaming, Lightning, and Lifedrinker are all level 5 weapons, and Lifedrinker especially jumps out at me as something good for a defender (5 temp hp every time you drop an enemy).
I also believe that you just need to wear a holy symbol to use it ... I'll check tonight when I get home, see if I can find a page reference. You'll probably want the holy symbol for your dailies still, though. It sucks a lot when you miss with a daily.
Well ... I've probably babbled enough now. Just kibitzing, pointing out some options if you want them. I'll polish my rogue up a bit tonight or tomorrow morning.
