My friend tebtosca is a really good writer, and her stories and recaps introduced me to SPN when I wasn't even watching the show! I started reading the fic and then had to start watching the series. LOL
I'm more partial to J2 stuff, since I don't really know the Sam/Dean backstory, but she writes both, in addition to other pairings on the show, and, more importantly, she recommends a TON of fic. If you check out her "fic" and "fic rec" tags on LJ you will see a bunch (not sure exactly what you like, so I'll let you explore and find what turns your crank).
She also co-mods an LJ comm of Sam/Dean recs: [Unknown site tag]

All of her work can be found on AO3 as well:
