Firstly, I would recommend picking up a PHP framework. This will help you immensely to quickly code your site.

An understanding of MVC is essential, a user friendly PHP framework I would recommened is codeigniter.

It can be found here. Good luck.

You may try out Drupal CMS for your project as it have thousands of add-on modules and designs to let you build any site you can imagine..
