How to upgrade this team?

[shasty mcnasty]

I'm off to a decent start, but i've got Chris Shelton burning a hole in my pocket, and I'm wondering what position I should target to improve on my team. It seems that Weeks at 2B, Barmes at SS, and my SP are my biggest weaknesses. What position would you target to trade for Shelton if this were your team?
