I think the Master of Masters told him about some of the things in the book. But what Luxu knows about the bool is pretty much common knowledge (the light expiring and everything)

Well, considering that the Master Of Masters and Luxu were particularly close, I imagine that the Master Of Masters must have divulged some of the books contents to Luxu, but not everything! Like he said in Back Cover, he doesn't want Luxu causing any time paradoxes, so he sent him off to do his mission without the book's help! Which means that Luxu probably knows only what the master told him, and nothing more!
