Nope, it's not unlimited entry. They do, however, keep some entries aside to sell in the week leading up to the event should it sell out. If you do definitely want to do it then I'd sign up now.
Accomodation is quite easy to find on Alpe d'Huez itself, and I'd recommend the Tourist Office there as they are very helpful in my experience, as there are dozens of hotels and a lot of apartments and houses to rent.
