I admit it would be easier to use a "clapper" or the power up on power restore.  But I was going to use this project  to get started in microcontrollers.  So I was wondering how exactly I would go about using the XBee on its own, or any recommendations on a quality RX TX pair.

XBee is overkill.
I would get a pair of promini, a set of
RF Link Transmitter & Receiver- 434MHz
and run virtualwire to send the command from one to the other.

Transmit side, run 3.3V/8 MHz, powerdown sleep mode all the time, 3.7V LiPo battery, button push creates interrupt to wake up & send the command.

If you were to suggest where you are located in the world - we can suggest somewhere to order a cheap transmitter and receiver....
If your system involves lethal voltages/life critical/flamable elements - you probably shouldn't need to ask.
The Arduino != PC.
