Help me with my keepers? I need 10 (Piece of cake right?)

[Newkie]

Okay, I just got an offer of Tommy Hanson and Matt Holliday, for my Ryan Zimmerman and a late first round pick and a middle 4th round pick for next season.
At the moment, I have 4 first round picks, 2 2nd round picks, 2 3rd round picks, and 4 4th round picks.

Any help on the matter would be great. I will probably just drop Anderson and put him in the draft, and grab him back up with one of my 3 remaining first rounders, or drop Alexia Ramirez and put him in the draft, as the guy drafting ahead of me has Sterlin Castro.

Thanks in advance
