Madara has Rinnegan, yes. He awakened it a little before his death. Kabuto is gone though, and since the jutsu stopped, everyone that was brought back to life using this jutsu was supposed to go... However, Madara is the only one that didn't go back. He performed a seal that separated Kabuto and himself, freeing himself from Kabuto's control and jutsu. So the only way to get rid of Madara is to either seal him, or kill him.
