After you select your flights for a non rev it takes you to a screen where you select the people that are traveling on that itinerary. When you hit continue it takes you to the screen where you confirm your name, date of birth and sex (if you have to take your pants off then you know you are in trouble). If you look at the last column on the right it allows you to put your trusted traveler (global entry) number into the non rev listing. Once you enter the number, Travelnet remembers it for future use.

TSA Pre Check is only available at selected airports, mostly the bigger ones, but as long as you list with your trusted traveler number it is good at any location. I have used it in CVG, DTW, LAX, DCA, ATL, and maybe some others.
