If I understand you correctly ,what you ask is not impossible. However most of the things you ask can't be explained in a couple of sentences especially not if you don't have enough knowledge of the program to understand the explanation that would be provided. They could be demonstrated and explained to you in anything from a few minutes to half an hour.
I'm sorry to say that my French is far from good enough to be able to even provide the short answers let alone the detailed long answers you need. Your best bet is to see if you can find a youtube about bill of material options, particularly show-hide-promote
