Now, if you can help me out with getting around the 'admin/' path taking me to the webserver control panel and not the CMS control panel, that would be great!

I have read that changing the '_config.php' file in the '/cms' directory allows you to change the 'admin/' path to whatever you like ie 'cmsadmin/'. This works fine to log onto the CMS control panel, but when I go to click on pages to the left, it is still pointing to 'admin/' (and not 'cmsadmin/' in my case) and therefore gives me a page error cos it can't find the pages.
