My robot uses the rover 5 to drive around. Currently I am using bluetooth to connect to to the EZ-B, but I find that the distance is very short. I have heard that X-Bee can have much greater distances for connection. (Seen As for large antennas exist for XBee. My robot needs to travel a distance away from me, and the 100m distance with bluetooth has not been enough.

My question is, what all would i need to use the XBee, and how can this be done. Please be specific with step by step, as for I am only partly experianced. I would like to get as much distance as possible and the XBee offers up to 80 Km in distance depending on the chip that you get. Even 1 Km would make a much bigger differance than the 100 m limit. I know that this can be done, as for the bluetooth has to come off and XBee goes on. But do they require another Xbee and the XBee Explorer? If so should I be buying the developer kit, as seen here

Also I am using the camera from the EZ-B website, can I connect this to the XBee that I place inside my Robot so that it can have good distance too. If not can it have a separate XBee that connects to the one attached to my computer? (if that is how XBee works)

Specific instructions on how to do this would be great, for more detail on what I am doing see here, also if you can help me with my laptop battery issue you will make my day!
