How would you tell apache that your content is in usr local www?

In your VirtualHost you can point Document root anywhere. The first VHost is where it points if the name that accesses the server is not included in another Vhost.

Eg.

<VirtualHost *:80>

ServerName google.com

ServerAlias www.google.com

DocumentRoot /where/ever/you/want/to/go

</VirtualHost>
