From that list, I'm reading The Windup Girl now. It's pretty good.
A Canticle for Leibowitz is one of my all time favorite books. There's also a sequel, but he doesn't appear to have read that.
Recently I read the series "The Entire and the Rose" which I really enjoyed. Martha Atwood's "Oryx & Crake" and "Year of the Flood" is a pair of dystopian books that might be my favorite story right now. For relatively hard Sci-Fi, Sean Williams' Astropolis series is incredible in scope.
