This question addresses how many halachos there are in Mishneh Torah.
How many chapters are in the Mishneh Torah?
How many books are in the Mishneh Torah?
Exactly 1000 chapters. This blog post on Giluy Milta B'alma by Dr. Ezra Chwat provides manuscript evidence that Rambam deliberately adjusted the MT to have this many chapters.
There are 14 books, I don't know the other statistics.
