Sounds like you have a bridge-burning course of action laid out, and don't have a question. Why the post? Need validation that your plan will let you ride into the sunset looking a cool guy anti-establishment hero, leaving the rest of the suckers behind?
Hint - it never works that way. You only get to monologue and rant to your boss then heroically fall on your sword (quit) in the movies. It generally doesn't sound nearly as cool when you do that in RL. Mostly it makes them fill out the employee termination paperwork as if you were fired for cause instead of quitting, and that makes some things harder in the future.
Sorry if this sounds harsh but you've probably been daydreaming for a while about the day you'll get to tell them to suck it, and the fantasy is a lot larger than reality in many cases. If you're going to go down that road, you gotta go big. Example - a guy I knew tried to do that sort of thing to his boss when quitting a motorcycle sales/repair shop. The boss chucked him out of his office before he really got started, so instead of finishing his "I quit" speech he went to the showroom, tossed a motorcycle through the storefront window, and only THEN could he ride off into the sunset as the rebellious anti-establishment cool guy. He was unemployed for months after that, and the only good thing that happened was that the boss reported the broken glass as random vandalism instead of going after the quitter for the replacement cost, so the insurance company probably paid for most of the repair.
