Your question somewhat depends on what items will be included in the price (tuition, fees, etc.).
First, I would not use comprehensive here. All might be a better substitute
I would call items for educational purposes (books, text, recordings or video-tapings, CDs, etc.) that contain lessons or matter to study, as course materials.
I would refer to items (protractor, special paper, pens, etc.), necessary to complete class projects or homework as "supplies."
I would refer to notebooks, writing pads, pens or pencials, items necessary to take notes, etc. as stationary supplies or just stationary.
I might also say something like "the cost (tuition, fees, etc.) for the course includes study material and stationary supplies."
Perhaps you could combine both: course material and stationary supplies are included in the price.
