SS is going to be a problem for you, as Furcal will be out for quite some time (I'm in the same boat in my H2H). Guzman may keep up decent numbers, but I wouldn't bet the house on it. Renteria is available in a fair number of leagues, he is a guy you may want to consider picking up if you can. He should heat up with the rest of the Tigers offense.
Weeks might be worth keeping, but only if there is nothing on the WW that is better, which in an 8 team league I doubt. The only other spot in your hitting I would worry about is the second UTIL, where Beltre is right now. Beltre isn't going to produce any better than what he's shown, not in that lineup. You may want to consider making a move for another bat, unless you want to wait out Thome.
Your SP's look good, though if you trust the past as indication of the future, you may consider moving Haren (notorious second half collapses, especially in W and ERA). He would be a valuable trade piece that should fetch a hefty return. Also, I would definitely try to sell on Colon. He started off last year at like 5-0 but followed that up with a record of 1-8. He is a major candidate to collapse at any moment. I would hope for one more solid start, and then try to move him.
Other than that, you should be fine once a few guys start hitting. Good luck!
