definitely pitch the yeast in the fermenter once the wort is cooled under 70-72 degrees, and after a good period of aeration. Also, while I absolutely loved "The complete joy of homebrewing" (it was the book that really taught me to brew "back in the day") I'd recommend picking up John Palmer's "How to Brew" to get a more up-to-date book on brewing.
Papazian's books are really good for beginners and are fun to read, but they're a bit dated and have some errors. So I second the recommendation that you go with "How to Brew."
BTW, if you're using a bucket, sufficient aeration means stirring your wort vigorously for at least 10 minutes once it gets to pitching temperature. The idea is to get oxygen into the wort to encourage yeast growth before the yeast gets around to fermenting your beer.
If you're using a carboy, sit on the floor with the carboy between your legs, hold it by the shoulders (not the neck) and gently rock it back and forth so the the wort splashes around. Do this for at least 10 minutes. Sitting spares your back and gives you better control over the rocking motion. Alternately, you might be able to get the handle of a long spoon into the neck of carboy and stir with that, but rocking the carboy works better.
