What's the best place to start learning about the languages and models GCD
supports? Links to public web pages are ideal.
(Apologies if there's something as simple as a table of links in the
README.)

I'd start with these:

Overviews:

http://developer.apple.com/mac/library/documentation/General/Conceptual/ConcurrencyProgrammingGuide/Introduction/Introduction.html

More on Blocks:

More on GCD:

http://developer.apple.com/mac/library/documentation/Performance/Reference/GCD_libdispatch_Ref/Reference/reference.html

Ars Technica also covers blocks and GCD from the 10,000 foot level as part of their enormous SnowLeopard review if you're looking for a non-Apple intro.
