Weaponry in the racial desc refers to any specialized weaponry that the species is specifically known for- like the Dwarven Urgosh in the Pathfinder books. As to the -2 to hit, its just the bite that gets the penalty generally. I'll get the Dwarves in the next pass too. I'll look into the movement thing- you're likely right on that, and I'll fix it when I read things over better. :)
