Jeter and Lopez were a little early, but getting Harden, Beckett, and K-Rod so late were great pick ups.
Depedning on what's left I would maybe look at filling 2B. Guys like Castillo, Durham, (if healthy
) Walker, and Roberts are great value options later in the draft IMO so you may be able to wait a couple more rounds.
Other than that, I think your pitching should be OK for now, I'd go back to landing some solid bats.
