Just google "Xbee raspberry pi" - you'll get loads of information about how to use it.
Same goes for "raspberry pi video streaming" - just google it.
What are you planning to use as the flight controller for the quadcopter? If it's the raspberry pi, then that's a much bigger piece of work than video streaming or Xbee. I'd do the big stuff first, and then worry about little details.
