Is this the first direct observation of 2 neutron stars colliding?No, many have been observed via their gamma ray burst (GRB), and some even associated with a visual or X-Ray afterglow.
I would say that this is the first collision of 2 neutron stars where the source of the resulting GRB and afterglow has been positively identified.

20 second delay in detecting the light sourceIt was only 1.7 seconds, so you can add an extra zero to the refractive index of space.
