Roster Help...Make a trade or stand pat?

[typoneg]

I have had a rash of injuries/suspensions. I have aramis hurt, manny suspended, and I had to drop my top two closers (Soria, and Francisco) because of this. I have a good, not great lineup, and very thin bench, and excellent starting pitching. Do you guys think I should trade from my starting pitching, or continue to use its strength.
*5x5 head to hear league with 8 teams. Scoring comprised of r, hr, rbi, sb, avg, w, k, era, whip, saves:

team

c ianetta
1b a gonzo
2b utley
ss bartlett
3b cabrera
of kemp
of ellsbury
of rio
util k morales
bn votto (out with ear infection)
bn m ramirez (suspended)
dl a ramirez (shoulder, back who the hell knows)

sp lincecum
sp haren
rp lidge
rp s downs
p greinke
p bedard
p cueto
bn e jackson
bn oswalt

Should I?
*Stand Pat
*Drop jackson for best of avaliable
*Drop Oswalt " "
*Trade one of my big 3 Lincecum, Haren, or Greinke

I would test the market for Grienke. If this is a keeper league or not. Sell him at max value right now. As we just saw he isnt unhittable. Although it was only 2 earned that could progress. The others I would stand pat on and maybe check to see if you can get value for Oswalt on name recognition because he is def. not getting any run support to get W's.
