You didn't mention if you'll be plowing for yourself or others so i'll share my experiences with ya.
I've been plowing residential and commercial with my 95 equipped with 8' Fisher Minute Mount since new. Even with the plow prep package you are putting a lot of extra weight on the front of these beast. You also be putting a lot of stress on your front suspension and steering components (You WILL wear those items out faster), and greatly speed up the rate of body rot/rust.
The roads up here in New England turn more white from the salt they use on the roads than from the snow! If they do the same in MI, be warned, that stuff gets EVERYWHERE, causes binding in linkages and screws up electrical connectors!
Also, be careful if you decide to plow. These trucks have lots of torque and you can break things real easy when plowing.
The Boss plow is a decent plow and should not interfere with the intercooler. Just don't go around with the plow on when the outside temp is up.
If I was to do it over again, I would just plow my driveway only. Then again, a decent snowblower can put snow where a plow can not.
