The step-by-step explanation is attached.

1) How do we tell from the plot whether or not there is overshooting?

From the plot, the dc gain is 6dB. If there is no overshooting, the magnitude at the resonant frequency (at about 1.4 rad/s in this case) should be about 3dB lower than the dc gain, which is 3dB in this case. If ...
