[support] Views 3.3 How to build complex views

Hi, After some hours searching for documentation, I'm a bit confused about the new views interface. I have Drupal 7.12 with two content types : Server and firewalls, and customer. And I want to build a "Customer" page with views containing servers and firewalls for each customer belonging to that customer. What is the best way to do that ? Panel ? Views ? How to build that ? Thanks, Olivier.
