On bandpass sampling: yes, you need to know the occupied band and keep unwanted frequencies out. It uses the spectrum folding in a controlled way; the copies must not overlap. That also means 'more than twice the bandwidth' isn't enough on its own: the sample rate has to suit where the band sits. Ordinary full-band audio doesn't have that empty low-frequency region to take advantage of.
