Portfolio theory is described in section 3 of Chapter 20 of our Course Notes. You cannot be asked calculations in Paper F9 – just the idea of it (and the explanation of systematic and unsystematic risk).
The treasury function really comprises three things – the management of short-term cash, the raising of long-term finance, and the management of foreign exchange risk. I did not bother writing a new chapter on this because each of them are covered separately in the Course Notes.
