I recently purchased the patterns framework and from my experience stepping through the code should reveal a lot to you. That said, I would survey the patterns that are unfamiliar to you as you encounter them in stepping through the code with the included PDF open. The PDF explains where certain patterns are used but not what they are or why they are important. So, to answer your question: Yes, I would pull out one of the design pattern books which this framework has provided examples for and as you encounter the patterns used in the ecommerce applicaiton, I would look them up, study and step through the code in repetition to get a feel for whats going on.
