As well as installing the component and module I also added the following into the index.php

As James said, the Joomla manual will tell you the basics on how to install components and modules and enable them.
Just quickly to add to that, you don't need those includes in the index.php. In fact they are wrong and will only clutter your file.
When you install a module, you need to publish it in the Module Manager and assign it to an existing module position in your template.
When you install a component, you often need to go through it's configuration and set it up to your needs then, most of the time, it's simply a matter of creating a new menu item of type Component and choosing your installed component from the list.
