As a start, I found "The Complete Guide To High End Audio" Fifth Edition by Robert Harley very helpful as an overall guide to your questions. It is available as an iBook on iTunes. I refer to it from time to time.
It has a section devoted to cost allocations which is very useful.
The book has been the best investment I've made in Hi-Fi to date.
