All you need is a raspberry-pi, power cable, and sd card. Also you'll probably want a case unless you are happy using a box you already have.
You can buy this SD card usb adapter for £2 if your computer doesn't have an sd slot
Simply plug in the sd card, use the raspbmc gui installer http://i.imgur.com/WaUEDl.png
It'll only take a couple of minutes. Then you eject the sd card and plug it into the raspberry-pi, along with an hdmi cable and the power cable.
