The answer to this question could be tricky. For a simple answer you may take the bandwidth of a bandpass signal as $\omega_2 - \omega_1$ (highest minus the lowest frequencies), and don't care about what happens in between the two. Hence your bandwidth allocation is not fully efficient, and a sampling based on this bandwidth will include redundant ...

The filter order equals the number of poles, that's a fact. How people call and use parameters in software is a totally different question. Many routines that design standard IIR filters use frequency transformations to design bandpass or bandstop filters from a prototype lowpass filter. Often, the specified filter order is the order of the prototype lowpass ...
