Everything you need to know about PhotoReading is in the book. Nothing has been left out.
The Home Study course and Seminars are guided classes that help you experiment and experience the system in a structured way and it helps you to appreciate the learning curve with a bit more patience. They have the advantage of being a different experience when you do the courses again. Unlike a book the word on a page rarely take on a different meaning, listening to an audio course or having an instructor answer someones question somewhat differently than last time often helps things to click faster.
