How can I get the columns at the bottom, above the page number? Is that possible?

Sure that is directly possible without further tinkering:

\notebookpage{todo={[bottom,draw]3},fill dotted,paginate}

This will create a dotted page with 3x2 todo notes at the bottom. The todo fields are surrounded by a box (draw), and the page is paginated.

Perfect! Thank you.
