Correct Apache permissions

running on: CentOS
WPv: 3.1

I am trying to figure out what the best set of permissions should be for my wordpress directory structure. I have read the documentation on codex and it seems like a good starting point. but I still have questions.

My questions relate more to the following files/folders:
../www/html/wordpress/wp-content
../www/html/wordpress/wp-content/uploads
../www/html/wordpress/wp-content/plugins
../www/html/wordpress/wp-content/blogs.dir
../www/html/wordpress/.htaccess

What I have done is i changed ‘group‘ ownership of uploads & blogs.dir to the apache group and gave the directory 775 permissions. With the .htaccess file I also changed ‘group‘ ownership to apache and changed permissions to 660. I’m not quite sure what to do with wp-content. I have also noticed that I can’t make changes to certain plugins unless I give more permissions to the apache user in the directory of the plugins. Apache does not have any ownership (individual or group) under the plugins directory at all, the permissions are 755.

I almost feel like I should be asking some of these questions on the apache forums instead but given that certain functionality in the application is dependent on the permissions I figured I would ask here for some guidance.

Thanks,
