Wordpress plugin needed

I need a simple wordpress plugin that should be very simple and quick for someone who is familiar with wordpress plugins. Basically, I need a plugin that will do the following: 1. For each blog post, a script will create a separate page with that blog post on it. 2. This additional page will include the blog post itself, and also links to any PREVIOUS blog posts (as on a normal blog), but will not display any links to any new posts that are made after. 3. This page should show all comments that have been left on that post, and also should have a form to submit a new comment (as in a standard blog) So to summerise,? each post that is made on the blog will be given a separate url linking to a page with just that blog post (and comments) and links to previous posts but not later posts. people can leave comments on this page. I hope I have been able to explain this ok. Please ask me if you are unclear of what is needed.
