Reduce Request Serialization in W3 Total Cache

I just added a couple plugins (Sexybookmarks and WP Jetpack). I have an 87/100 Google page speed score which I think is good.
But, now I see 2 new ‘yellow’ signs in my Page Speed Report which I didn’t have before. Presumably, this is related to my new plugins? Yes/No?
I don’t know how to fix them.
So far, I have only tried clearing the cache. I’m not super good at understanding W3.
