I don't think I've ever printed 200 photos at a time (except for our wedding and honeymoon pics), usually I print off 20 - 30 (so they are sorta already in a theme).
I store my photos in those photo boxes. Before doing LOs, organizing them, I usually try to group them together (like all my friend photos of my birthday, than all my family photos, and then misc. photos, etc.).
Hope this helps.
