Answer 1

Available from Amazon.com - the title is

"Collins Scrabble Tournament and Club Word List".  It's a 2007 paperback edition.

Not sure where you are, but for me in the U.S., Amazon lists it as an Import book, and it's available used for $44.77 from third-party sellers.

According to Wikipedia, that's the book that's used for word judging in international tournaments and all tournaments played to the SOWPODS word list.
