While in Werewolf or Werebear form, you will still use the damage from weapons or ranged weapons. It's really just a graphical change. You will still be swinging your sword or shooting your bow, but it will appear as if you're hitting them with your claws. You will not gain the benefit of attacking from distances when using ranged weapons in Werewolf or Werebear form. Ranged weapons will work, but you'll have to move to melee range and use the ranged weapons like melee weapons.
