well, you can snag a Ki pool for the cleric via some of the stuff in Legendary Games' The Way of Ki. Iirc, clerics of Irori get Improved Unarmed Strike as a bonus feat (since unarmed strike is the favored weapon of Irori). No idea how to get a flurry of blows, but Style Feats are open to anyone, and there are lots of things which add extra goodies for kung-fu fighting. Little Red Goblin Games' Heroes of the East series and Dragon Tiger Ox both have martial-arts mayhem goodness.
I'm sure there's more out there, but I can't say anything about stuff I don't own...
