Dan, you don't need to worry about air PERIOD. It has a YSS rear shock that does not use air. It has Sonic Springs in the front that also don't really need air. Just ride and enjoy. Also, all the major maintenance is done. Steering head bearings have been repacked. Valves have been adjusted. Carbs have been removed and floats properly set.
There is a white cord on the left handlebar to plug the Ipod, MP3, whatever into that will play when the radio is set on auxiliary. Rear end oil was recently changed with Mobil synthetic. Engine has, and has always had, Mobil 1 Racing 4T. Current oil has about 100 miles on it.
The only think you might want to do is check the air pressure in the tires.
Just go for a ride already.
