Yes. One of the physical laws that describe orbits in response to a central force is the fact that the smaller the orbit, the faster the orbiting body travels. Earth's average speed in its orbit around the sun is 18.5 miles (29.8 km) per second. Mercury's average speed in its orbit around the sun is 29.7 miles (47.9 km) per second.
I will discuss both separately. The space shuttle does have a maximum speed of 17,500 mph, but that speed is relative to the Earth. If you think about the space shuttle's velocity relative to the Sun, then the answer is the sum of Earth's velocity plus that of the shuttle. This means that the shuttle is moving at 67,000 + 17,500 mph (84,500 mph). So the space shuttle actually does move faster than the Earth. However, the shuttle speed is actually irrelevant to your question, because the shuttle never truly leaves Earth's gravity.
