I have never seen inherited Naples before Wedding. Most of the time its either early wedding with subject Naples or Naples is already out.
Naples is 5 provinces only, even if Aragon loses the PU over Naples it still can easily conquer 11 provinces in 80 years.
You can still integrate them manually, you just can't pop a decision and inherit (not actually integrate, patch notes use the wrong wording) them for free.
Yes, that is correct but just I think it still should be possible to start counting 10 provinces after the inheritance fires and not 1444.
