There is a Live Journal community that does pairing character stories, like I read one, and it was a character study on Mustang, then a character study on Hughes, then the last part of it was how their characters interacted (in canon, so they were not real pairings.)
At the end of the posting they gave links to information and even links to fics, I believe.
They were really informative and would help me in this fic I am writing.
I am almost positive it was multi fandom and was not FMA specific, though there are at least a couple FMA listings in it.
Thanks again, all.
