Hi,
The 3 books by Dan Harrington are a series and together make up the complete package. Part one is the beginning of a tournament, part 2 is the endgame and headsup, part 3 is a book of poker situations - a quiz of sorts. I think that is right.
If you havent read it buy the Theory of Poker by David Sklansky - the only book you will ever need.
Amazon is a good place to get poker books from and I think Blonde have a link
Good luck

Harrinton isnt the be all and end all is the only bit of advice ill give you. But volume 1 is a compulsory read. Read some more practical MTT advice, Vines and McEvoy How to win NLHE tournies is good. Steer clear of the TJ/McEvoy books which really are an excercise in weak tight poker, more suited to well structured comps.
The best advice is free on the 2+2 forums. Also the short-stacked theory post on Andy Wards Secrets of the amateurs blog is A grade material. Hope you do well.
Is way too limit orientated and a bit too tough for inexperienced students. My advice, save this until you have a deeper knowledge of the game.
