Rns-e question?

[BBlackburn]

Hi I have purchased a rns-e unit comes on Monday, can't wait to get it fitted and working, the unit comes with the kufatech Bns navigation harness. Just wanted to know before I fit it all is there anything else I need to get it all completely working? doesn't specify an antenna, also I would like to use the bluetooth phone prep I need to buy the Bluetooth set up for that don't I? How hard is that to install?
Sorry for all the questions or If they sound like I have no idea because I actually don't my first a3.
Cheers guys
