i've wondered for a while now if naruto were related to the 1st some how but i'm not sure the necklace lady-T gave increases his own power. i say it's just fate. the others that wore the charm weren't meant to be hokage. yamoto is a descendant of the 1st and the amulet allows him to suppress the kyuubi's chakra but that's between yamoto and the amulet, it doesn't mean naruto is a descendant of the first. if the amulet were on a different jinchuuriki i think it would still enhance yamoto's ability to suppress it's chakra.
