By "they" zorro and luffy ment to include the other members of Teach's crew whom they understood that were watching frm around.Also the scar of Shanks was probably done by the claw type weapon that BB held in one of the flashbacks.

About the cerberus theory...although it would be cool, it is by now certainly impossible.It's a theory that has spread so much, that even if it was Oda's original idea he would have changed it by now so that he can hold the element of surprise and not have the whole fandome saying "haha i predicted it!"
