You will find a complete systems manual at the site below BUT it requires you to have a copy of their Excellent 744 FMC, EFIS etc trainer (cheap for what you get). Look at the aerowinx site and see the capabilities of their program. I have used it for simulator rehearsals and pre route checks and it has helped to 'suss out' the tricky bits
Another good book is Bill Bulfer's FMC techniques book. Found out things I didn't know even years after starting to operate on the beast.
