You also have to look at the jump from the previous season. CC threw 241 in 2007, not including playoffs. Lester had never thrown 200+ in a season (not just MLB).
Yes that seems right. I see Baldelli signing, and if we trade Lugo to get a catcher (or anyone else), I wouldn't be surprised if we nabbed Jerry Hairston.
He's never pitched above AA, and even in AA he had a 1.48 WHIP and a 1.93 K/BB. A team would have to be really desperate to use him in the Majors this year.
