There is no electronic information out there that is worth reading before reading the book, or as a substitute for it.
There are no tables or formulas for N+ and N- in the Zone System except for the ones that you make yourself. If you don't understand that, then you don't understand why you might want to learn about the Zone System in the first place!
I suggest picking up the book and reading it, and also taking it with a grain of salt. All it is is simply one way to go about exposure and development.
At any rate, it is not something I would start learning "just because". You should have a solid reason for it, IMO. This solid reason will come only after a certain degree of previous technical understanding and trial and error (mostly error).
I will paraphrase:
The book is easily obtainable. Try a few other sources.
Read the book first, as it lays out
the Zone System (a proper noun, mind you, so there
is only one system with that name) as it was originally intended to be laid out. Then start looking elsewhere. However, start with the book itself, or even just the single chapter on the Zone System. It is brief, well written, simple, original, and is the obvious "point A", from which you may later find points of departure.
The question about tables is something that you will realize was a silly question once you learn the first couple of things about the system.
Don't take the System as law or religion. Take it as one person's explanation of their methodology, which you may or may not find useful.
There is no reason to use the Zone System until you understand why you might want to use it. You need some experience with more standard methods to understand why you might want to use the System in the first place. If you are a total beginner, learning the Zone System is dangerous to your over all technical understanding, IMO.
