As to fore and aft position, depending on your frame spec for seat tube angle, set the nose of your saddle about 8cm behind the BB by dropping a plumb line. I prefer the setback of Hincapie which is almost 10cm and you may prefer to ride behind KOPS a bit as well...his legs are longer than ours and rides with a saddle height of 80cm.
That should get you close. Your riding position in the pic does not look correct with a huge stem height...perhaps due to too short a head tube but a two inch drop for the 'proper' reach is a very good starting point for many recreational riders.
