Question #2:

Use a class variable for $data to access it in more than one method of the same controller:

That will work if you want to use the data across the controller, but if yo have to pass a large amount of data like i do to the views to build the UI ¬°dynamically using a common data structure, you can use a Model to store the structure and logic of the data you'll be passing to the views, just a simple example:
Code:
// Data Model

class DataModel extends Model {

      function DataModel() {
        parent::Model();
    }
    
    private $foo = array();
        
    function set_foo($key='',$val=''){
        $this->foo[$key] = $val;
    }
    
    function get_foo(){
        return $this->foo;
    }    
}

    
// Controller using the Data Model

class Article extends Controller {

    function Article(){
        parent::Controller();
        $this->load->model('DataModel');
        
        $this->DataModel->set_foo('global_option', 'foo');
        $this->DataModel->set_foo('another_global', 'bar');
    }
    
    function index(){
        $this->DataModel->set_foo('title', 'Hello World');
        $this->DataModel->set_foo('color', '#003322');
        $this->DataModel->set_foo('sidebar', 'extended');

        $data = $this->DataModel->get_foo();

        $this->load->view('article', $data);
    }
}

That is a simple example but you can think it like and active record approach and even add some logic to it so it will auto-populate fields left blank with some default values, that's up to you.
