And why do you have that many Pages in your Manage > Pages? Yikes. Consider moving some of those to posts as not all 1000 Pages should be Pages. I moved my site from static to WordPress and I had a lot of debate over the difference between a Page and a post. I have over 700 posts and 17 pages. It required some rewiring of my thought processes to really get clear about what deserved to be a "Page".
For CMS purposes, any web page generated on your site is valid. The difference is in how you use the template tags for each as well as category templates. For example, if you want a fast list of the core Pages like "contact", "schedule/events", "about", etc, then having those as pages allows you to use the
wp_list_pages template tag to generate that core list.
Having the rest of your material as posts allows the use of the powerful category templates so you can customize each category page with how things are listed and provide more information specific to each category.
If you are using multiple authors, using the Author Templates allow custom information to be displayed along with the author's posts.
If you want to link to ANYTHING within a navigation or a page, referring to posts as pages or even linking to categories, see:
I hope that helps. And ColdForged Enhanced Post View is AWESOME and I cannot live without it. It would be nice if applied to Pages, but I spend most of my time with Posts.
