Improvement needed or should I stand pat?

[MushuCrew]

My lineup
C-Pierzynski,1B-Konerko,2B-Soriano,3B-Lowell,SS-Tejada
OF - Sosa,Matos,Huff,Baldelli,Lofton
UTIF - Teixeira
Bench - A.Ramirez,Hinske,Encarnacion,Dunn
SP - Hudson,Millwood,Webb,Beckett,Meche,Ponson,Suppan
RP - Wagner,Looper,Mears

I'm concerned about Looper's job security and my weak OF, I'm generally between 4-6 in most offensive categories but lead in SBs. My P has been pretty solid all year as I rank 3-5 in most categories there. Overall I'm in 6th but about 150-200 points away from 3rd or 4th place. Any advice on improving my squad?

Trade or pick up someone for your 1B

trade meche for a solid 1b

[Althalius]

can you trade Lowell and a bench player (perhaps pitch Suppans recent amazing game?) for Rolen and some OF help.
