Include global.php and then you can check to see if someone is logged in using something like..

PHP Code:

if($vbulletin->userinfo['userid']){
//User is logged in
} 


You can use the login form from the navbar if you want just make sure you change the location of the action attribute if your page is not located in the same directory of the forum itself.


^^Thats for the users aspect of it.

Now you said CMS too, so Im guess you would also want to use VB as the base of posting content for it as well. The easiest way I have done that in the past was just to create a couple of hidden forums for the different categories and then draw in threads from those forums to be displayed as content.
