wordpress.com or wordpress.org because they are almost two completely different things. one hosts sites with wp cms and one is the cms. assuming you've installed this yourself ill assume you mean .org

delete your DB and all content from your public_html
upload the contents of /wordpress/ from wordpress-3.0.4.zip
dont create a dB via cP, let wp create the dB
prefix, name, server, pw -- all match.
also before you start over, check your htaccess or just delete it to make sure it's not limited anything.
as far as file permissions are concerned:

Name File/Dir Needed Chmod Current Chmod
root directory../0755 755.
wp-includes/../wp-includes0755 755..
htaccess../.htaccess0644 644.
wp-admin/index.phpindex.php0644 644.
wp-admin/js/js/0755 755.
wp-content/themes/../wp-content/themes0755 755.
wp-content/plugins/../wp-content/plugins0755 755.
wp-admin/../wp-admin0755 755.
wp-content/../wp-content0755 755.
all else fails it probably is your host.
