Can someone help a newbie out?

You are getting an error when you just go to "site" because you don't have an index method in your Site class, which is what gets loaded if no method is used in the url.

Site should be "Site", not "SITE" in your class declaration. CI_Controller, not CI_controller.

Your other errors are because you have a semicolon after "data" and are using & where you should be using $ in your variables. You left the $ off of data. Those are very basic php things. Are you sure you are ready for CI?

Code:

class Site extends CI_Controller {

  function index()
  {
    //load some default view?
  }

  function contact_us()
  {
    // Wrong: &data;['main_content'] = 'contact_us';
    $data['main_content'] = 'contact_us';
    //Wrong: $this->load->view('template', &data;);
    $this->load->view('template', $data);
  }

  //make the same changes to about_us() as I did to contact_us()
}
