the permission denied error is definitely a filesystem permission error. You should make sure your folders are all 755 and your files are 644 permissions inside your public_html folder. Joomla! by default should have had the right permissions set, but it sounds like something is awry.

The 500 error could be caused by a number of things. A good place to start is to rename any file named .htaccess in your public_html folder to something like ~.htaccess. If the error goes away, you have an error in your .htaccess file and you should seek more information from Joomla! how to fix this.
