So I've looked in PHB1 and 2, as well as all over the internets, and I can't find a clear answer.

I play a level 12 Dreadnought Fighter, wearing Rimefire Plate armor. The armor gives a static "Resist 1 All," and my Dreadnought Path feature "Dreadnought Action" grants me "Resist 10 All" when I use an action point to attack. After spending an action point, would I have Resist 11 All or Resist 10 All?

I also have items and a power that can grant me resist all. Do any of these stack? I've been playing it as they don't, but I'd love if they did.
