Well, just because Castiel is cut-off from heaven doesn't mean that he is human. He is still an angel possessing a human, however, he lives by the limitations of his human host because he has no powers of his own anymore. Remember, Anna had to fall and rip out her grace to be an actual human. Castiel is simply a depowered angel. :)
Uhm, I didn't actually pay any attention to Sam's weapon. And if he was using Dean's gun, then I don't think it has any deeper meaning. Dean's gun is a normal weapon, Sam was presumably going to face demons and against those the gun is useless anyway. And the infected people he killed with it could have been killed with any other weapon as well. So, no I don't think it means anything. :)
