Shalimar is still pretty much alive and kicking, so to speak. You'll find many discussions on the subtle changes between batches, but I think most people believe that the latest batch is still good. (Also, remember that it comes in different concentrations, parfum, edp, edt).
As for the others, I haven't smelled the vintage. They seem to be big florals. Since you live in SF, my recommendation would be to stop by places like Barney's, Chanel boutique, Diptyque whenever you get the chance, and spray yourself. It may take some time, but so many things have appeared in the past 20 years, and your tastes could have changed.
Just randomly off the top of my head - things that could be in the general neighborhood of green, aldehydic, floral:
Chanel exclusives (in the boutique): No. 22 (aldehydic), Bel respiro (green floral), La Pausa (iris), 31 rue cambon (elegant floral)
Diptyque: Eau lente (floral spicy)
Malle (at Barneys): Lys mediterranee (white floral), Carnal flower (big floral).
Amouage Gold (enourmous aldehydic floral. don't know where it could be found in SF, though)
My favorite green floral is perhaps Metal by Paco Rabanne, it's cheap but hard to find. Anais Anais is a soapy rose, cheap and easy to find.
