Of course at this point there's not much else left to help their team. If they had this cash the whole time they had the entire offseason to find a better way to use it. Like adding all of Uehara, Adams and keeping Burnett whose combined 2013 salaries are the same as Soriano's. Or any other combination of moves that makes them significantly better than just adding Soriano. Uehara alone is probably more valuable than Soriano for this season.
No, when xFIP is an entire run better for an entire career it is completely worthless to use it to rank a pitcher regardless of how fast it normalizes. I agree that it's an overpay when compared to the other RP'ers this offseason but their entire roster is pretty much locked in for 2013 and 2014. Morse and Haren are the only significant FA's. At the end of the day this is about saving Boras's butt. They keep him happy since he represents several of their big name players.
