Hey Man CapeX5 is not over-reacting..These cars don't do well with hacked up wiring. Many of the car's systems are inter-related, and it's possible several of your codes are related to bad wiring...You should fix that first. I would.

These cars very rarely have a problem with a bad throttle body. I would not replace it just yet.

That cracked hose is a vacuum or vent line. You should pay extra attention to vacuum leaks and fix those first. They can lead to a whole host of codes, including some of the ones you got. You might consider a smoke test to help you identify vac leak.
