Is that good or am I missing something?

Or do I need to run new ground wires to all my speakers then into the new stereo?

I'm a little confused.
the original radio has 2 common grounds: on left side speakers AND right side speakers
so you can add 4 new ground wires or retain the originals just for the rear and add 2 new ground wires for the front
and you should add a new wire for the radio light..
