  1. w = 2 * pi * f_s

  2. since you need to sample at 2x or more the highest desired frequency to get proper reproduction, it should be w>2w_s

  w > (1/2) w_s
  w > (1/2) 2 pi f_s
  w > pi f_s

    You need to sample at 2x the desired bandwidth, just bandpass filter the signal appropriately before sampling and you won’t get aliasing.
