Dan01 I would never just delete a page I would 301 the page to another page on the site that has the same or very like content. Do you want 1000 or how many pages you delete 404's. There was a rule a long time ago never just delete a page we call this linkrot, and not something I would do.
You can as suggested noindex them but if the pages are duplicate in nature I prefer to 301 them myself.
