I'm not 100% sure on this since its been weeks since I completed that mission, but click visit next to the person's name after you input their code. Then hit invite. That should do it. (unless they need to accept your invite first) As for sponsoring, there's supposed to be a special area for you to sponsor one and only one player. I thought it was on the social->invite tab. I think the "sponsor 10 friends with your friend code" requires other players to sponsor you. I gave up on that mission a while ago. :P
