I bought a domain name and hosting from GoDaddy yesterday but I'm having a bit of bother setting up my content site in Joomla...

Everything seemed fine after I installed Joomla, I was able to type in the URL in my browser and it brought up the homepage. I then installed a different 1.6 template, which went okay, except all of the template isn't there, just the header, background and a few other bits n pieces. Here is what it looks like: whatisthatallabout.com
This is what the template should like: Home

Can someone tell me why mine is being displayed differently and what I need to do to create a catagory list as a menu down the side?
