I understand the fundamentals of Einstein's theory of spacetime. What I don't know is how much faster time would be in a space without objects, say in comparison to the speed of time on Earth. Since the weight of our planet stretches the fabric of spacetime a specific amount, the time on the planet is slowed to a specific speed. How much is time slowed by our planet? How big would a super-massive black hole be to slow time to a point that time doesn't progress? What is the normal rate of speed for time if nothing slows it?

Well, I can't actually find a straight number to give you for how much the Earth speed and gravity affect time (probably because it's such a small number and varies depending on altitude which affects how much gravity you are under). But here's a couple of links that describe the math if you want to figure it out yourself.

As far as the black hole goes, if you are talking about crossing the event horizon (and thus not coming back) then the answer is zero. Even if you could come back from the event horizon, time will have effectively been stopped for you while you were there. The same goes for flying exactly at the speed of light.

It's a little confusing, but you are using "rate" and "speed" which are both based on time. Time itself cannot HAVE a "rate" that's a misconception. If the speed of light alters but distance doesn't then time must alter.
