I'd say drop a. everett. I looked up his stats and he's a 6 year player so I think his history should be a good indicator of what he's capable. He's got good numbers right now, but according to his stats, he's likely to level off and won't provide very good stats.
Any of those starters look good that are available. I just can't say which one is best between kazmir, cabrera and blanton. Cabrera is known for his inconsistency, but probably has the most upside. Kazmir has good k's, but i'm not sure how serious his injury he recently sustained is, and he pitches against the powerful al east teams a lot so that's a negative. Blanton hasn't looked good this season, but had a good year last year for era. But for the most part, I'll leave that up for others to put in their 2 cents on the starters.
