The reason that Bristol advertise the costs separately is that some people will be sitting the course without the mandatory brush-up classroom sessions. These are people who are exempt due to having another ICAO licence and, I think, over 1,000 hours. Anyone else, sitting ATPL for the first time will have to pay the full course price (which will include manuals) although I believe it can be split into two modules.
Second hand manuals aren't worth that much but if, post-PPL, you wanted to start studying straight away before you wish to enrol on a course (as there is a time limit between sitting the first and last exams), then the notes may be useful.
