I wouldn't worry too much about too much oil. I did that a few times by checking the oil cold and then putting too much in. The trick is to check while the car is up to operating temperature.

Green color coolant is fine although the system should be regularly flushed.

On pic #3, is that coming from your instrument panel? It looks like your speedometer cable. Are you getting an accurate speed rating and is your odometer/trip timer working?
