CMB for non-Strength weapon attacks.

If I have Weapon Finesse, can I apply my Dex bonus to my combat maneuver checks instead of my Strength bonus??

It depends on what combat maneuver you're attempting. Disarm, sunder, and trip are normally the only kinds of combat maneuvers in which you’re actually using a weapon to perform the maneuver, and therefore the weapon’s bonuses apply to the roll. Therefore, if you're attempting a disarm, sunder, or trip maneuver, you can apply your Dex bonus instead of your Str mod on the combat maneuver check (assuming you're using a finessable weapon, of course). For other combat maneuvers, you use the normal rule for determining CMB (Str instead of Dex).
The Agile Maneuvers feat applies to all combat maneuvers, not just disarm, sunder, and trip, so it is still a useful option for a Dex-based creature that uses combat maneuvers.

Is this a special rule for Weapon Finesse, or a general rule (ie, if attempting a combat maneuver with a weapon, you use whatever stat you're using to hit with that weapon to calculate your CMB)?

For example, a Sensei Monk can use Wisdom to hit with his unarmed strikes. If he was attempting to trip a foe, would he calculate his CMB with Wisdom instead of Strength? Why or why not?

The Insightful Strike ability specifically says the Sensei monk uses his Wisdom bonus for combat maneuver checks.

Oops, bad example, that'll teach me not to do my research. Substitute the Guided Hand feat instead.

Sure. But that only applies to Disarm, Sunder or Trip, with your deity's favored weapon.
