Sounds like the injectors may be bad or just really dirty. You say that the truck is only used as a plow truck, so I would assume that it sits alot. If you dont add any fuel stabilizer to the tank, the fuel will start to degrade and the will gum up your injectors. One thing you can do is to pull the air cleaner assembly off and look at the injectors while the truck is running. Look at the bottom of the injectors while it is running. The injectors shouldbe spraying fuel with a fan spray of fine mist. If you see any drips of fuel in the this fine mist, that injector is at least dirty or on its way out. I would recommend that you change your fuel filter and then get some fresh fuel and the purchase some Seafoam fuel injector cleaner from your local parts store. Dont mess around with anything else. GET SEAFOAM. If it is in a plastic bottle it is not strong enough to do anything. Seafoam is in a metal can. Dump the seafoam in and run the truck as much as you can. This will help clean out the injectors.

it should be at the maximum high pressure. airbag pressures were reduced only recently due to lawsuits. if you mean air suspension, it might be rather hard to locate the settings. try contacting Chevrolet itself or, if the air suspension is an aftermarket, its manufacturer to help you.

does that have a third brake light ( one on back of cab) if that one don't work then it more than likely brake light switch (on brake pedal) or fuse.
if that one works but other ones dont more than likely bad ground

Your belt routing should be on a diagram on either the fan shroud, or the core support. However, this routing depends on whether or not your truck is equipped with a/c. Either way a belt routing diagram should not be difficult to locate.
