Can't take 10 on saves...1 is always a failure.

You sleep with a guy who stinks, you eat breakfast with him, you travel with him, you can safely assume you'll end accustomed to his scent. Hence the "take 10".

Crane style is only here for the necessity of provoking the first AoO with crane riposte, and the master can have riposte @lvl2 (irrelevant here but anyway). However you can always add some styles to have a greater punch, juste pick the one that pleases you. I'm personally fond of crane riposte + snake fang. I agree MoMS is not needed, but the OP was talking about it.
Int 13 is always an issue for someone who tries to do some maneuvers anyway, but if you have paired opportunist in the team, any guy that attacks the monk will end up prone, and maybe dead.
Quick calculation of the trip AoO at lvl11:
human (20 point buy) : 19/14/10/13/13/7 (+1str lvl4, +1wis lvl8)
trip = 11(monk lvl)+5(str)+4(paired opp)+4(trip feats) = 24
She can trip a CR11 gold dragon on 11+, naked, without flanking, buffs and such.

PS : If not done already, take a look at this guide ;)

Consider the stampede ability as well. 3 aurochs are superior to 1 bison. There is plenty of use for more lesser summons.
