The last 2 issues should be related to a couple of switches for the brake pedal. IIRC, one cancels cruise control and the other is the brake indication. It also serves as a feature to prevent unintended acceleration (cuts power). The switches can be adjusted, but with that mileage you might as well get the switches replaced.
Once all is said and done you'll notice the engine will scream like you've never heard before in a long time because the throttle actually opens up now. Reference my post in this thread:
