For your second question, go stand on the weapon. Press select and then look if it says that's two-handed or single-handed. If it's two-handed you should set on you support ability on the Ability that sets that you can carry a two-handed sword. For a Soldier that ability is called: Monkey Grip and can be learned from Vigilante and the other one is learned as a Fighter ability: from Venus Blade and it's called Doublehand
