If you're looking for Flaw suggestions, I can offer Shaky (-2 with ranged attacks) and Inattentive (-4 to Listen and Spot checks).
A Warblade does not often need to switch to ranged weapons, in my experience, so that's not such a bad area to be weak in. And a touch of preening narcissism is just the thing for ignoring one's surroundings - to better keep an eye on looking sharp, of course.
Given any thought to what you'd like your character to be able to do? That'll guide your feat and maneuver choices better than suggestions I could make based on mere utility.
