The entire MVC approach will surprise you and make you think differently, not only more on classes, but also directory structures. Basically, an MVC application (as I understand it) uses a single index.php file in the root and then points downstream. Basically, the index.php is the boostrap and redirects everything from there to individual controllers, which will control whatever action is called from the boostrap. On initial glance it seems pretty simple. We'll see...

There's a good webinar on it from some of the architects here. If it doesn't bore you to tears, it's pretty good information if you can sit through it.
