Your “pages” are archive pages based on category. So you’ll have to edit the archives template in your theme so that it shows the full post or a thumbnail. (It should be archives.php in your theme files)
This might help if you want to go that route:

Alternatively, you could create page templates for each category. Just copy your index.php file, and then add the code at the top to make it a page template, and then change the loop so it pulls only articles from each category.
Here’s the how-to for that:

This is the archive.php
what do I add?
Oh, and I also need to know something else.
I want only a few categories on the HOME page which is hip-hop music, videos, and news… how do I go this. I want everything Indie to be only on the indie page, and not on the home page.
