Voldemort can split his soul into as many pieces as he has committed murders. He chose seven because it is a powerful magical number. There is a spell that must be cast to create a Horcrux, and no evidence that he was able to cast it before the Avada Kedavra reversed on him. This does not necessarily rule out that Harry is a Horcrux, since it is fact that some of Voldemort's powers transferred to Harry when the spell backfired.
I think the key to removing a Horcrux within Harry himself is the power which Harry has, that Voldemort does not - Love. Voldemort cannot possess Harry because Harry's love is strong and causes Voldemort pain. I think that Harry's ability to love will factor into this book, as it was very prominently mentioned in the Order of the Phoenix.
