Gravity is currently thought to travel at the speed of light.

Is it possible, in theory at least, to use gravity to transmit and receive information as is done with electricity and light?

In theory, it's possible, but in practice it would be devilishly difficult (and would require an engineering expertise which is almost impossible to imagine). Almost the only events that produce gravitational disturbances that we could hope to detect are collapses of stars into neutron stars or black holes, or the orbiting of a neutron star around a black hole. So we'd have to figure out a way of using such phenomena to send gravitational signals.

I'm not holding my breath over here.

It's not strong enough to provide a good signal. The EM spectrum is far superior.
