Look into MY_Controller (search the forums, there's plenty of posts on it)
You put all the common functionality in there, any anything you want executed on every page, you put in MY_Controller constructor. Then any controllers which extend this will execute that constructor.

You can also acheive the problems with the views using MY_Controller, or if you need something more advanced look into a template library. You could also use a master view with the header/footer, and just load the content in the middle
