I watched my copy of the DVD for the first time last night, was excellent, I've been burned loads of times with rugby DVDs but this one is great. The best DVD since the 1997 Lions Tour.
The Alan English book you mentioned is well worth getting too. There's also another book by Ciaran Cronin I think that has match reports for every fame since 1997. Really good too. Don't get the Eoin Murphy book, it's very poor.
If he doesn't have it already the Alan English book about 1978 is really good too.
In terms of getting it signed, I don't think there are any signings this weekend because of the Munster game although you could try and get it signed by someone at the game.
