whoo, lots of excellent fic. I haven't seen the movie (or any of the related stuff) but I've somehow fallen into Clint Barton(Hawkeye)/Phil Coulson shipping, and there's a whole lot of good stuff out there for that.
A really popular series that's more general and not as particularly Clint/Coulson shippy -- and is a LOT of fun -- is scifigrl47's Toasterverse: Phil Coulson's Case Files of the Toasterverse (or anything by her)
Fic recs on LJ's Crack Van (will have a variety of ships): Crack Van fic recs
A fandom overview (info about the movie and the fandom as a whole, with a list of Avengers-movie-related comms and other sites: Crack Van Avengers fandom overview
I should warn you though -- most of the fic I've read has had tons of major spoilers for the movie, and the tumblr mentioned above does too, as does the Crack Van fandom overview.
