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 templete, which went okay, except all of the modules or template isn't there, just the top part of the home page. Here is what it looks like: whatisthatallabout.com
This is what it should look like: http://www.themegoat.com/j16/?template=autodealer-et

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