Best way to fill on the money, get a gallon of your preferred oil.
Buy yourself an extended oil filter (eg:Mobil-1 m110, Bosch 3320, etc.).
Drop the old oil semi-warm, fill new filter 2/3 full and let soak into the filter media then reinstall. Take your gallon jug, and pour 1-1.5 small funnel full into the filler with the drain bolt still out (pushes more of the old stuff out). Put drain bolt back on, and put the rest of your gallon in. This methods always fill me to just a little above the halfway mark.
As for your over-fill, if you want to know if the bike is truly level when you check the window, put a small level on top of the gas tank and then check. If you're overfilled, do what beefsalad says and crack the filter to let some out.
