This is not, in fact, a handbook.
Gotta say, it's not bad if you get full casting from Sacred Fist. And yes, you can do that to counter. Easier to just punch them, though - not only would the spell fizzle, but they'd take yet more damage.
Only go for Clositered Cleric if you can use Knowledge Devotion, otherwise, what for? Losing BAB and HP for fun? I'll get told off in a sec, but I don't see 2 skill points being worth it for you here.
To get into Sacred Fist after level 6 (not earlier with 3/4 BAB), you'd need +4 BAB. You get none from Monk, so 5 Cleric levels have to do that, and they can only do that if you use partial BAB, as you should, and don't take Cloistered Cleric.
Are you sure you'll need Divine Magician? Sure, it's not bad, but some domains are really nice.
You'll also want Spontaneous Domain Casting for some domain and a dozen other Alternate Class Features, but you can read all about that here: http://brilliantgameologists.com/boards/index.php?topic=420.0
Holy Warrior (CC feat) could be nice, but you'd need the War Domain. Weapon Focus in Unarmed Strike is an added bonus, along with decent spells.
Time Domain is also awesome, in so many different ways. Haste/Contingency/Time Stop/Imp. Initiative... What's not to like?
Destiny is VERY nice, especially at higher levels.
Bestial would give you an attack and damage bonus.
