It's good that you are trying to seek resources from outside the classroom. But remember, that during class it will be hard to keep up if you are using a different textbook/resource. Here's what I suggest.
With your note taking, use the study design as your guide. It should be your bible for the next 9 months for each of your subjects. For each dot point in the study design make a heading and subheadings from each further class in the dot point. This allows you to cover everything you can be examined on. Now under each heading and subheading is when you can use your vast variety of resources to collate the best possible information you can use to help you revise.
On a personal note, at the start of the year I went on a rampage and bought so many study guides and resources and by the time i finished my exam I had barely used 50% of the stuff I had bought. Point of the story is that once you start getting in the deep end of year 12 you are fairly limited for time so you need to get things done properly, but also efficiently. This means that you might not use ALL of the resources that you have on hand, but maybe just 1-2 to extract what you need.. and then move on.
