Is it possible to make my Samsung Galaxy Nexus use external usb storage like memory sticks? Is it possible to make my Samsung Galaxy Nexus connect to a USB memory stick?

I have the USB Connect. How can I do that?
If your Galaxy Nexus is rooted, install this app: StickMount. Then connect your USB to a USB-to-MicroUSB cable (such as this one), and plug the micro usb into the phone, a popup will appear asking you what application do you want to open, select StickMount. Using a file manager, such as this one, navigate to: /sdcard/usbStorage/ you will find your USB files there.

Note: If your phone is not rooted, you cannot do this.
