Sabean admits to discussing trades for shortstops, including Jason Bartlett and Marco Scutaro. Jose Reyes is a name that has been rumored to be available, but the Mets have a steep asking price of 3 or 4 prospects, which will probably keep the Giants out of the running. The Giants have also been rumored to be interested in Miguel Tejada who might be a better fill at 3B than at SS due to his declining range as he ages.
I would prefer to bring Uribe back; even if he doesn't match last year's power totals, his .256 BABIP was much lower than his .282 career mark so his average should improve a tick. Uribe was above replacement level defensively as a SS last year, and has also posted a positive dWAR over his career. He can slide over and play second or third in a pinch, and he also provided us with the "Lot of happy" quote and the jazz hands home run trot.
