I like your list. I think arguments could be made for Moustakas or LoMo...and I think Kendrick and Jones are the two that could be replaced, but I'm not sure I would change anything. I still think Jones has more upside than he has shown. I don't love Kendrick, but he gives you great positional flexibility, so that adds to his value. I like LoMo better than Moustakas in 2012, but in the long run, I probably like Moustakas better. Plus, you aren't currently keeping a 3B, and that position is a little thin (though Hanley and Miggy will add to the depth this year).
All that said, for this year, I probably keep the players you have listed, and look to grab a few high ceiling players in the draft that might not hit their potential in 2012 (e.g. Moustakas) so you can keep them next year when you keepers expand to 10. If you can keep some known quantities (Jones, Kendrick) and redraft LoMo and Moustakas, that's a win-win.
