I'm not a good max/maxxer. I don't do mathematical analyses to figure out what will get me the best possible character. The linear variability of D&D can pretty much take care of built-in superiority right quick, anyway.
I also know that some think trying to min/max with a monk is a joke.
With those disclaimers, I found you can make a pretty sweet human monk/cleric combo in Eberron. Take the War domain with a deity/pantheon/philosophy that grants longsword as a favored weapon. You get Whirling Steel Strike by 3rd-level easily (with a total of seven feats, one taken by Monastic Training [cleric] if your DM requires it).
Where to take it from there depends on your desires. The fighter class and judicious feat allocation could certainly bring this character into a monster number of attacks and a very decent BAB.
My two coppers.
