Advice for buying Xbee module

hi guys,
i want build small 4 wheels rover controlled using wireless xbee modules.
i’ve never used these modules before , i’ve read guides on internet order right components write , test personal sketch whole project. components shipping usa europe it’s important buy basic components need future testing.
which hardware need? thinking buy:
-2x xbee module (2mw series 2) – thought i’d take series 2 because consumes less , newer series 1, let me know if i’m wrong.      https://www.sparkfun.com/products/10414
-2x arduino – arduino n.1 in transmitter , arduino n.2 in receiver
-1x explorer usb – configure xbee settings https://www.sparkfun.com/products/11812
-other accessories (such as: usb cable, breakout board xbee module , headers)
how configure xbee modules?
i thinking set them serial communication; example:
arduino n.1 read input (from button or joystick) , send message arduino n.2 receive , (control motors go forward or backward…).
i’ve build mini robot (with arduino) moves along room ultrasonic sensor measures distances obstacles , walls.
