You have a steep learning curve ahead of you. I will try to put this in context for you, in the 2000 there is one command for the basic settings of the system, Command 08 and depending on which of the 2000s you have there are over 400 sub commands each of which can change the way in which your system works. You don't change a lot of them on an install but you need to know which to change and that is just the beginning.
That said, as Belvedere says, ask specific questions and we will do our best to guide you through the maze. Everyone has to start somewhere.
