1. Be quick with your membership application, it can take a while although my membership card arrived pretty quick (around one month from ordering it until getting the welcome package).
2. I don't know if you can order your tickets via
http://www.listicket.it/ . They actually state at juventus.com that you can order it on that website although a lot of people tell you here that you have to actually call the guys in Italy.
3. Keep in mind that you can
only order tickets in the pre-emption process for
yourself and not for your friends who do
not have that premium membership (which honestly is the biggest scam ever EVER compared to German soccer clubs and their premium membership)
4. The membership is still kinda worth it. You get the hurra juventus mag for your apple/android products, discount at the shop, for tickets and for the J-museum(if you ever actually visit Torino) and a crappy membership website with useless videos and other informations
