I'm not sure such an index exists, but Mikkeller does a single hop series if you can get it in your area.
I honestly found one of the best ways to learn about individual hops was to collect 6-7 gallons of simple wort (90% 2R, 5% Munich, 5% C40), and do 5-6 separate boils, each with a single hop. Usually makes a decent beer too!
Plus, you now have an idea for a blog!
Honestly though, its probably brewery to brewery. For instance, a newer brewery in Baltimore (Union - very limited distribution) uses all Galaxy hops in the APA. Not sure if that is on the website, the owner told me at the launch party, so you may have to do some hand-to-hand research.
