I've got a very parallel situation on one site and I did nothing to try to control indexing (and I'm happy with the results so far - 5 years on.)
If I were going go to do something, I wouldn't bother with the canonical link. I'd use a meta noindex, and open the content area of the questions page with a single big old link that says: "These questions refer to the information at [link]." That's going to circulate link equity in a natural and very effective way.
