Brian (BHoody) and Peakbagr are certainly correct. The guide is alright to give you a general feel, but if you try to follow the direction "to the tee", you will certainly get lost (lord knows I have).
If you look around, there are plenty of places to find information online. Ask on here, you'll likely get more info than you need. Best of all, most of the internet stuff is free (as opposed to the book). I've found, people are more than willing to share specific info about hiking if you want to ask specific questions.
