Does gasoline become "stale" when stored for a long period? If so, what is happening, chemically? Are additives sold to prevent this from happening effective?

It will, gas is a mixture and over time the more volitile compounds will off gas. Oxidation will happen over time as well. If the gas contains ethanol it will also grab water from the air. There are fuel stabilizers avalible like Sta-bil.
