You only need a volume for editing segmentations. Some Segment Editor effects would not need it, but it was easier to just make this a prerequisite for segmentation.

Correct.

Correct. Since image resampling is a lossy operation, and it is particularly bad for binary images, it is better to avoid changing geometry of existing segmentations. However, a one-time cropping and resampling to isotropic spacing before starting segmentation is usually beneficial.
