Help me decide if I should make a deadline trade in FF?!?!

QB P. Manning

WR P. Burress

WR J. Porter

RB T. Barber

RB L. Johnson

TE H. Miller

W/R S. Davis

BN A. Bryant

BN T. Bell

BN L. Smith

BN C. Benson

BN Ro. Williams

BN B. Johnson

This is my current team. What I was wondering is should I now trade away Tatum Bell that Larry Johnson will be starting? I think it is pretty clear that I should try and get a solid WR for him but let me know if you think something different. Should I maybe offer Larry Johnson instead and hope to get a stud WR in return and then just start T. Bell everyweek, or just save T. Bell on the bench in case of injuries? I have no clue what to do and help with be appreciated.

PS This is my first time playing FF so they is probably a good chance this is a stupid question.
