First Fantasy League... Need WR Help!!!

[soonerinnebraska]

I'm in a 10 team, Yahoo PPR League (QB, 3 WR, 2 RB, TE, K, DEF). I had a friend draft for me and I won my first two match ups, but I don't know what to do WR/RB-wise. Here's my entire lineup:

QB: Philip Rivers, Matt Ryan
WR: R Wayne, M Clayton, TJ Housmandzadeh, P Crayton, E Bennett, A. Gonzalez
RB: F Jackson, M Jones-Drew, Sproles, M. Barber, B. Wells, J. Norwood
TE: O. Daniels, H MIller
K: Kris Brown
Def: Packers, Ravens

Who should I get rid of WR/RB-wise? Any other recommended roster-maintenance?

Thanks
