Cay, if you want network-manager to manage your wireless connection you will need to remove the wireless-essid and wireless-key lines from your '/etc/network/interfaces' file. When network-manager is managing your interface the essid and wireless-key will be stored in your gnome- keyring. Using network-manager will allow you to store information about wireless networks without having use multiple interfaces files.
