Eon by Alison Goodman has a warrior-sage female protagonist with a disability. The whole story revolves around the society she's in forcing her to pretend to be a man in order to even have the chance of achieving the status she desires. Also political turmoil, tons of honor and morality-based problems. There is eastern magic involved, and for the love of God, don't read the second book if you don't want angst.
Also, The Blue Sword by Robin McKinley was one of my first female protagonist fighters. I read it again just recently, and it held up to my expectations well!
