I know nothing of wrestling but the tabletop nature of it and the idea of running them outside of matches sounds kinda awesome

Is there a single book I can read that can give me enough context on the subject?

"The Squared Circle" by David Shoemaker is a really good overview of the sport and its history up until the modern era. 
"Death of the Territories" by Tim Hornbaker covers the NWA and its eventual demise at the hands of the WWF.
"We Promised You a Great Event" by Bill Hanstock covers mostly the WWF/E. It's an unauthorized biography so it's very much warts and all.

Squared Circle would probably be your best bet probably.
