Questions about Powermac G5 Networking

I've recently bought a used Powermac G5 on ebay, 750GB HD, 1.5GB ram, 1.8GHz, and it's a 2003 model I believe. (M9393LL/A A1047 to be exact)

But, It doesn't come with any airport card, or antenna. I've searched on ebay, and found the right airport card (extreme) but I've seen a few different antennas.

Is this the correct antenna I need for the wireless and bluetooth capability? I have to have bluetooth because I'll be using wireless keyboards.

if that is not correct, please link me to one that will work.

And, just for your knowledge, this is the airport card I'm going to be buying.

Hmm, what is the bluetooth module called?
