Think you have to go Bautista, Kinsler, Hamels. Need to keep atleast one ace pitcher, believe Hamels would be better choice than Dickey. Austin Jackson is an under rated player, but 2B is too shallow to not keep Kinsler. Have to hope Bautista stays healthy.
I think you definitely have to keep both Fielder and Bautista. Fielder is the only guy who give you a .300 avg 30+ HRs and 100BBs. The BBs stat make him even better.
For the third player, Kinsler or Hamels. Hamels is great on WHIP/ERA/K/Ws and is right there in QS. The only thing to keep in mind is his 24 HRs allowed. Of the top 15 pitchers (based on wins) Hamels was tied for highest HRs allowed in 2012 at 24 (funny enough, the other guy he was tied with was Dickey). That being said, his BB was better than average for the group.
Kinsler's not bad and he's a doubles machine (best of your keepers). Between him and Fielder you would have two guys in the top 50 in that stat. Unfortunately, his triples are low and if get yourself the "right" speed guy, he should bring in both SBs and triples.
I'd say Fielder, Bautista and Hamels for this particular format, though the case can be made for Kinslet. But hey, if you pick up a guy like Markakis along the way, you'll be on your way on 2Bs for a much cheaper cost.
