Is this all I will need?

My apologies James C4S as I may have over stressed the point slightly, it's just that all my results for, 2 arduinos comunicating via xbee, showed results where they comunicate via a terminal program of some kind.

And thanks Chargrin for this information as I thought the adapters where optional. So am I looking to buy 2 of these as well then?

Also why is it that this board does not come with header pins, just soldering holes?

Thanks!
