"3. In Realband - get tracks as good as possible..i.e. volume and panning.. remember to listen "

This one I'm not entirely sure matters IF you're dropping into another daw. If a tracks volume is at -10 and hard panned to the right, will that carry over with the drag/drop? Not really sure and I haven't tried. But I make it a practice to have tracks all the way up and panned to center, both in biab before opening the song file in real band, and in real band before I drag tracks out. A little investigation would tell the story.

If you're mixing within real band, or any daw, then yes- gain and panning matter a great deal.
