From you requirement i can infer that that you are trying to build EBook kind of functionality in sharepoint. I could think of the following two options :-
Option#1
Create the entire EBooks as bunch of html with full-fledged navigation including table of contents, index etc outside of sharepoint environment. Once you are done with EBooks html (created outside of sharepoint), you can host the EBooks html in the document library of sharepoint and render the ebooks in sharepoint using PageViewerWebPart (IFrames). This is simple and quick approach. It has few disadvantages also.
Option#2
The other option is to completely author EBooks content in sharepoint itself. In this case you need to do custom development for page layouts, master pages, workflow (for approval), custom navigation controls for Left Navigation and Global Navigation. In this approach you cannot quickly bring up your EBooks site. But it has many other advantages. Also you need to define the content life-cycle process from authoring to publishing.
I don't think with MOSS 2007 also, you can completely eliminate the manual authoring process. None of the CMS tools will give you 100% automated process for creating EBooks for such 1000 pages of magnitude.
