What about if I am moving two armies into province P, from A and B, and the enemy moves his army OUT of P, into A. Will he fight my A army alone, or will I get to pound him with both armies together, or will they harmlessly pass each other by?

I think when enemy two armies will cross each other's path, the game picks one of their provinces as the one to hold the battle in. The army that "hosts" the battle gets the benefit of home ground (domain and its pd, I think), but loses its movement for the turn (if it wins), so that it remains in its original territory. I don't know what factors decide which province the battle would be in. (I can imagine it being anything from army size to army speed to programming mechanics like the order the provinces are numbered in).

So that said, if the A and P armies cross paths, the battle may resolved in A or P. I suspect that if the battle occurs in P, the army from B would also be included in the fight, while if the A/P army battle happens in A, then B's army ends up attacking empty province P, while A's army fights P's army on its own.

That's my guess, anyway.
