Help me keep my team in 1st place!

[BravesGuy]

Hey guys. Ive been holding down the top spot in my Head to Head league for most of the year and I feel like there are a couple moves I could make to solidify my team.

Here are the stats R, H, HR, RBI, SB, E, AVG and W, CG, SHO, SV, K, ERA, WHIP. And there are 10 teams in this league with 2 dead managers.

My team is full of Stud batters and pitchers. ARam, Helton, Weeks and Cantu are my not so good players. Especially Weeks since my league counts Errors.

C J. Mauer (Min - C)
1B C. Delgado (NYM - 1B)
2B J. Cantú (TB - 2B,3B)
3B T. Glaus (Tor - 3B,SS)
SS M. Young (Tex - SS)
OF G. Sizemore (Cle - OF)
OF C. Beltrán (NYM - OF)
OF J. Damon (NYY - OF)
Util R. Weeks (Mil - 2B)
BN T. Helton (Col - 1B)
BN A. Ramírez (ChC - 3B)

SP D. Haren (Oak - SP)
SP Ra. Johnson (NYY - SP)
RP B. Jenks (CWS - RP)
RP J. Nathan (Min - RP)
P J. Putz (Sea - RP)
P Jo. Santana (Min - SP)
P C. Schilling (Bos - SP,RP)
BN P. Martínez (NYM - SP)
BN R. Clemens (Hou - SP)
BN J. Bonderman (Det - SP)
DL B. Sheets (Mil - SP)

There are a few big name/good players sitting out in the FA pool:
Ha. Ramírez (Fla - SS)
Jh. Peralta (Cle - SS)
G. Atkins (Col - 3B)
M. Thames (Det - OF)
I. Kinsler (Tex - 2B,SS)
T. Iguchi (CWS - 2B)
J. Gomes (TB - OF)
B. Bonds (SF - OF)

A. Pettitte (Hou - SP)
R. Dempster (ChC - SP,RP)
A. Benítez (SF - RP)
K. Escobar (LAA - SP,RP)
E. Guardado (Sea - RP)

Do you think I should just stay put with the players I have, pick up a FA, or try and make a trade?
