Using Ultrasonic Range Finder along with XBEE module - is this possible?

I'm developing a project in which I have a self made sonar system on the front of my DF Rover for collision avoidance and then I have a xbee shield along witht the xbee module to go with my set up. What I want to do is use the xbee for communication between my two rovers and communication from my laptop using X-CTU. Is this at all possible and would anybody out there have some example sketches I can follow just to have an idea of what to do? also when I attach my xbee shield to the arduino board it gets in the way of my VCC and GND slots so I can't plug anything into the red power slots next to the analog because the xbee shield is covering it up. How do I get around this?

 

Thank You!!!
