You'd need to fire the rocket to slow down sufficiently to fall into the sun right?

Just imagining the solar system as a bowling ball at the center of a trampoline surrounded by fast moving billiard balls. The problem is probably the speed the earth is moving at, plus the speed we had to get the rocket up to, to get it off earth.

Yes, which is around 30 km/s of delta-v, as compared with only 12 km/s delta-v to boost an object from Earth's orbit (assuming you launch it in the same direction that Earth is traveling) to escape velocity from the solar system.
