Do VLC and Skype also use PulseAudio, right? Are these accessing PA natively, or through alsa-lib pulse plugin?
Yes they do, natively.
I'm quite sure about the "natively" part. Not 100% sure because until yesterday I didn't really know how components from the sound stack fit together. I did some reading and I think I get it now but you never know... As proof that PulseAudio is accessed natively:
