As wet clutch plates expand they shed material due to friction which will get into the oil and can cause premature wear to bearings and other parts in the engine. Also, due to the oncreased number of plates necessary a wet clutch requires a harder "pull" in order to engage and disengage.

Clutches only create heat when they are slipping.

Um, no.

Friction creates heat. Whenever the clutch engages and disengages it creates friction between two surfaces being slowly (or occasionally rapidly, eh Ebbs?) moved together or apart. That generates heat. Not as much heat as if the plates are worn out and they slip, but it still generates heat.

Interesting... I'd expect the opposite. More plates = more friction (though maybe the oil negates that) and so less squeezing force is required by the springs to get the same amount of total friction out of the thing.

The squeezing force is separating the clutch plates, so other than that you're right. The "squeeze" separates the clutch plates, and more clutch plates means more effort.
