Is this step really needed? If not, is there a way I can avoid this transcode? If it is needed (or preferable), can I safely delete the large MOV files after I finish editing? Can I then easily re-create them if I need to make further edits?

You can delete the Pro Res files after finishing projects.
They can be re-created easily.
