I'm currently waiting for my dad to sort out a hub for me so I can actually connect to Live. The ethernet socket on my wall only has one plug in it which is being used by my PC, so a hub is needed. If I dont have one sorted by tomorrow I'll just take my PC offline for the day and use the port for the 360 though
As for a gamertag. Im not so sure on this issue. I created one weeks ago on xbox.com (SSXAnubis), however I dont know yet whether I'll actually be able to use that one. The leaflet in my console pack says that I'm entitled to a free month of Gold, and to get it just create a new profile during setup. But if I used my SSXAnubis profile it wouldnt be new...so I don't know if I'd get the free month.
I've sent in a support ticket on the website to ask anyway, so hopefully I'll get a response soon. I'd like to keep using SSXAnubis whilst its created, but if I cant get my free month with it (since I set it up more than a month ago now) I'll be making a new one.
