You get this message because of the missing IP address. As Gred
mentioned before, you should change the ordering of your resources in
your "Apache Service" as following.
                <service autostart="1" domain="httpd" name="Apache
Service">
                        <ip ref="192.168.1.7"/>
                        <fs ref="apache_content"/>
                        <script ref="cluster_apache"/>
                </service>

Well this seams all be correct. But the service rgmanager aka clurgmgrd
is one of the last services which are started at boot.

That's right because your service never started.

You can mount gfs using fstab but it can already be done using the
GFS-ressource. If mounting your filesystem using fstab you don't need a
resource.

Read http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/ for more
details.
