I just finished upgrading my Look 585, wanting to keep a classic appearance.

New
Dura Ace 9000 shifters, FD, RD, Cassette, and chain
Gravitas SL brakes with Reynolds pads
Fizik Antares Braided saddle
Vittoria Evo SC Tubulars

I originally planned to set it up as 10 speed, but I was able to recycle the titanium 12/13 one piece cogs from my KCNC cassette. I had a local machine shop reduce the shoulder to 2.18mm and recessed the outside to allow me to use a 11 tooth Chris King lock ring to attach it. It changes flawlessly, and the only gear not usable without front changer rub is the 36/12. I had a long enough axle, but a washer should allow anyone else to do the same thing.
The post is repainted, cables routed for clean look with reversed braking.
In case anyone was going to comment, there is no pressure on the top tube from my stand.
