Question

Answer 1

The duplicate entry is for a key made up from 3 fields, id_path, is_system and store_id, in theory you should be able to use URL Rewrite Management, search for an id_path of product/19 and this is your 'troublesome' field. Deleting that value may solve the issue (but I'd recommend making a backup first, and trying it in a dev environment first).

If you are still in development and haven't used any custom rewrites you could just empty the core_url_rewrite table and re-index to regenerate all the fields. If it is a live site this would be a little more troublesome, it would mean losing a bit of SEO juice if you have renamed products, since you would lose the rewrite.
