there isnt really such a thing as "too much" for power wire... the bigger wire will restrict the current flow less,and in general help out. while a smaller wire will stillwork, id just keepthe bigger wire,leaves you the option of upgrading equipment,added help on your charging system, and you dont have to spend more money buying new wire...

same goes for the fuse... fuse the wire for the wires abilities... your equipment should be fused, if not, fuse it near the equipment for the manufacturers specs.
