Props to the Guru(s), Potential Trade Advice Needed

First I'd like to thank the Guru and his colleagues for all their advice so far, while its still early, my D is #1 in my league by a long shot.   See my team below.  

Because I drafted Manning, I now desperately need to upgrade at QB, and I know I can probably get a good return on Laurinaitis or Timmons.  I'm sure their recent bad games are anomalies, but which of the two would you consider trading, and would you be comfortable with Bishop as your #2 the rest of the way?  Are there any other IDPs on my roster that you would consider "selling high" on?  

As always, thanks in advance.
