Re-start the posture thing:
1) Raise the bars so the tops are level with the saddle.
2) Rotate the bars up so the ramps are almost level with the ground - or totally level.
3) Adjust the saddle so you don't rock.

If you are riding with your elbows straight, move the saddle forward. Don't be too concerned with Knee Over Pedal unless it bothers you. If you are still having discomfort while in the drops, measure your drop distance on the bars and get a set that is 5" or less. For maximum comfort, the drop grip should almost clear the top tube.

In fact, for people with these complaints, I suggest a read of Rivendell's Grant Peterson. His idea of riding a bike may be refreshing.
