I haven't even bought this game yet but it's still exciting to read about your progress! I'm glad you're feeling better. I'm definitely picking this up when its finished.
As to making a book of tables I think that's a great idea. I have a dungeon crawling game where the rules are in one book and all the tables are in another. It makes playing it much easier. The other alternative is to replicate all tables at the back, but that ramps up the page count. Your final option is to merely reference the tables in the main text of the book and have all the tables grouped at the end of the book. I have seen all of these options and all of them are great. The only choice I wouldn't favour is not picking one of them as any table heavy game can lead to a lot of bothersome flicking backwards and forwards between pages.
