Well, two things I see that are killing you right away. Helton and Lowell. Helton has no protection. People aren't going to pitch to him. Lowell is struggling. With Vlad on the DL, your offense is hurting. I would consider dangling Vlad out there and see what offers you get. Don't trade him right away, but see if you can get a bid war started and reap the benefits. Only downside is that Vlad is an OF. There is usually plenty of good OFs, not as good as Vlad mind you, but usually good ones.
You can drop Holliday from your list of hits out there. He just broke a finger. Crisp or Encarcion look like the best option of the three. However, there might be some hitters that are buried. Willy Mo Pena just got off the DL, and if he isn't on a team, grab him. The Big Hurt is playing again, and already has 2 Homeruns. Might not be a bad option.
But it looks like the DL is what is killing you. You have three good pitchers on it, and Vlad. See what people will offer for Vlad. I'm sure they will ignore that he is on the DL. He is slated for return soon.
