The trailer package is usually the receiver hitch and additional wiring for trailer brakes and 12 volt power[to charge break-away batteries and trailer power] There should be a red and dark blue 10-12 gauge wires that are in addition to the stock wiring harness.
The spring select is which torsion bars it has for the given weight rating as equipped. The c36 heater is the rear heat. Not all suburbans have rear heat and a/c.
The NZZ off road skid plates are the aluminum skid plates between the bumper and 1st crossmember,front differential skid plate and transfer case skid plate. A suburban may have a fuel tank skid plate as well.

Ok, thank you Yes there is at the options list fuel tank plate listed. Has that aux rear heater it´s own heating element or does it use also coolant from engine or how it works?

The rear heat uses engine coolant the same as the regular heater does. There is aluminum coolant tubes that run outside the frame on the passenger side to in front of the rear wheelwell. The control for the rear heat should be in the overhead console.
