does it keep slowing down as you move away from the earth's gravity? what's up with that? (pardon the pun)

Yes there is a time difference, it was one of the early science experiments that NASA did on space shuttle. Two high precision atomic clocks were used. One stayed on Earth and the other went up with space shuttle and returned. The two clocks were off slightly. Here are couple links that explain all his theory.

Yes, it has to be synchronized frequently with the clocks at Mission Control which are synch'ed frequently with the atomic clock at the Us Naval Observatory.
Time in a moving frame of reference travels slower than one in a "stationary" frame of reference, also time farther away from the center of a gravity well move more slowly. The moving far away frame of reference is the ISS, the "stationary" center of the gravity well is earth. Even a clock on earth but at the top of a very tall tower/building or mountain will measure the rate of time as passing more slowly compared to one on the ground.

It is very important to use a comparison...the clock itself would run at the same rate as when it was here on earth. What you need to specify is would a clock on the ISS run at a different rate than the same clock set in sync with a clock on the earth's surface. Years ago scientists conducted an Atomic clock experiment to test that very theory. According to Special Relativity...the closer one is to a source of gravity...the more space and time have a tendency to "drag" for lack of a better term. The idea is also expressed in a theory called "The Twin Paradox." The idea is that if one twin remained here on earth while another left on a space expedition that travelled at near the speed of light. When the space twin returned from the expidition only a small amount of time would have passed for them, however for the twin here on earth much more time would have passed. The cause is from an idea called time dilation and is derived from Special Relativity. Basically when travelling as speeds near the speed of light...or near the event horizon of a black hole time slows.
This is when it's important to remember your frame of reference! If you are in a car that is driving 55mph and you see a car that is driving in a parallel direction at 65mph. It would seem to you as though you weren't moving, but the other car was moving away from you (or toward you) at 10mph. However from the other cars perspective it would seem that it wasn't moving, but it was you who was moving BACKWARDS at 10mph! The same idea applies with time. If time slows for you it would appear that the rest of the universe was speeding up around you.
that's why scientists commonly say "It's all relative." B/c speed, accelleration, time and distance are all relative to the point of reference.

No, actually it would run faster. As you move away from the Earth's gravitational pull, you move slower than the Earth, and that compromises the 17,500 mph that you are apparently moving at. If you were 1 AU away from the Earth and not near the Sun, time would move just noticeably faster, but hardly enough to make much of a difference.

According to Albert Einstien, the answer is yes. The closer one travels to the speed of light, the slower time passes for them. Granted, the speed of the ISS (roughly 17,000mph) is nowhere near the speed of light (670,000,000mph and change), it is still affected by this principle. The extreme tale is of the two twins, one of whom remains on Earth, while the other is aboard a spaceship travelling at near the speed of light. When he returns to Earth, he finds that his brother has become an old man, while he has only aged a few years.
If you are looking for more details, feel free to ask.

Compared to earth the clock on ISS runs FASTER.
The earth clock is slower because it is in a higher gravitational potential at earth surface. Its called gravitational time dilation.

A clock has gears and gravity doesn't effect that.
