As for why the Dwarves have heavy armor, I'm not sure about that one. But yea, if you've completed the quest, "The Eye Of Magnus," I believe there was a book or note that told how the slaughter at Saarthal was centered in one area in particular which was the start of the Nord invasion/downfall of the snow elves.
