If it was simple, no-one would care about it.

You need to refine what you want to know. Number of pages is merely {memory,swap}size/page-size. All of those vary (yes, you can have different page sizes in the one system) - and each architecture is different.
Same (similar anyway) applies to page tables. Largely hardware dependent - Intel have some good white-papers on their MMU design; which, of course, may vary depending on chipset.
I used to have some reasonable links - I'll see what I can find on my old machines.
