Chaos Daemons, Monstrous Creatures, Weapons

Okay, so I have a question. If I take a Lord of Change with a Staff of Change (STR +2, AP 4) does my Smash rule confer AP 2 when using the Staff for regular attacks? How does this work?

I am pretty sure that monstrous creatures get AP2 all the time. This overrides the armor piercing value of whatever melee weapon they are using while still allowing access to the items special rules. Pretty sure... might want to check the rule book section for monstrous creatures.

Although now I am suddenly imagining a carnifex taking a vicious swipe at a catachan trooper only to reveal a sparkling, unmarred flack jacket and a grinning guardsman.

Yes, Smash overrides lesser APs. You can infer this from the fact that Smash specifically does not override AP1 weapons; if Smash didn't override other APs generally, there would be no need for the caveat.
