Hi Rich,
welcome aboard! Isn't it nice to know you are not alone in this crazy dream of becoming a pilot?!
As for the book, it's a little dated in it's info (mid 90's) but the general advice for preparing for interviews and aptitude tests is good. It also will give you an idea about what to expect at interviews. But to be honest your time will probably better used with the search function here on PPRuNe. There's a whole wealth of advice and information here. And if you have any questions just ask - there's bound to be someone here who knows the answer.
Hope this helps.
Good luck,
