Absolutely needs both.
One thing about skipping is that I will sometimes accidentally press a button and the cutscene will skip. Which sucks ass. I like games that require several presses or at least a specific button in order to skip, because it prevents accidental skips. If I'm sitting here hammering away at XYAB, it's pretty clear, game, that I want to skip.
The only thing worse than this is being forced to watch a cutscene over and over again. Even if I've yet to see it, there's no way to know that I haven't seen this same cutscene many times at a friend's house.
As far as pausing goes, shit, sometimes we need to take a piss break, man.
