If things are being hanged, check also your apache error log (probably somewhere like /var/log/apache/error_log, or at least that's where it is on debian, don't know about cent os).

The permissions you listed above are fine if apache is running as the deamon user. What user apache runs as depends on your os. If its running as some other user, than you'd need to change the owners of those files to whatever user apache runs as. Generally however a permission problem should not cause the webserver to hang, so you might have some other problem.
