If you get such a thing as wind, or a pressure gradient, PV=nRT no longer works. We're assuming the gas is in a static condition. Also, yes pressure is related to temperature but not exclusively so.
Gas molecules/atoms in "normal" conditions neutral with the electrons canceling out the charge of the nucleus. If they were charged, gosh... I can't imagine, gases would fly off into space or something and a little wind could cause all electric circuits to blow.
Temperature is merely a macroscopic property that manifests as a result of collective microscopic events. By the kinetic gas theory we can say that the temperature is the average kinetic energy of the gas. Energy can be in the form of electrical, kinetic, or due to the prescence of other fields, ie gravity. However, gases in average non-ultra high temperatures are always in the ground state electrically. The only energy that ever changes is its mechanical energy which is in the form of translational and vibrational energy. If there is just one atom comprising of the gas molecule, then there is no possible vibration mode, so there's only translational energy, therefore it would be safe to say that we can relate the gas's average speed to its energy.
