if there is intelligent life there and they point a telescope at us right now, they would be seeing earth ~ 500 years ago.

"check out this planet, looks like a promising place once we run out of materials here."

The planet is 1,400 light-years away. They'd be seeing earth at around 600AD.

by the time our today's signal reaches that planet, we ourselves will already be there to listen to it :)

FTL Travel?

of course. We know that it is possible - the light speed is the limit of speed only in fixed metric space-time, and the Universe itself shows that non-fixed metric space-time(expansion/contraction) can produce FTL speed - just look at all those far galaxies running FTL away from us. It is just a "simple" matter of engineering of local space-time metric geometry changes :)
