I think Pacos book is worth having just for the bits that you don't know about, yes it has some stuff that some of us aren't interested in but the PofF stuff is good, I can't remember if there is any peformance stuff in his PPL one but that is woth having the Professional book for as a reference.
Shawns book is excellent, but a bit too much for the newbie student. I read it when learning and didn't understand half of it, now I find it an invaluable reference when teaching or revising.
You are bound to find some bits that you don't understand or disagree with, the good thing is that you can always email these guys and I'd bet that if its wrong it gets changed in the next edition. The same cannot be said for some of the older texts produce by some national authorities which are quoted as Gospel and still wrong.
