Hey Bill, that would be sweet if you put together a trail guide resource like that on a website. I think it would be a lot of work for you initially, since it sounds like you've been damn near everywhere in the park. But once you got the site up and going, it wouldn't be that difficult to update it with new places you check out.
I found another site that is somewhat similar to what you propose: http://www.thebackcountry.org/trailhead.php
I traded a few emails with the creator of that site and he seemed like a decent enough guy. My complaint with that site is that he sticks to the trails and doesn't go cross country much, and that's the real info that I'm always curious about.
