I've been and seen Juve a couple of times, and am planning another trip this season.
I usually fly Ryanair from Stansted to Turin, you can get flights very cheap, they usually cost around £40 return, just check out their site for prices.
Last time I went I stayed in a small hotel in Turin, it was cheap (not much more than a tenner a night) and it was very good for the money. I don't recall the name of it, but it was central and not far from Via Garibaldi - where I believe there is now the official Juve store.
Turin is a nice place, so you've have no problems finding stuff to do, last time I went for a week and went and saw Juve train virtually every day - which was quality. That was when they trained in the Communale, I haven't been to the new training ground yet so I don't know how close it is to the city centre.
I got my tickets for the match in a newsagent (or an Italian equivalent to our newsagents), it was close to the stadium but I'm sure you can get tickets anywhere in Turin - I only went to the ground to buy tickets because that is how I bought them the last time. They were easy to buy, they had a plan of the stadium there so I could see exactly where my tickets were and exactly what I was getting.
And, as I'm sure you'll know the ground is never full so getting tickets isn't really a problem.
Hope this helps.
