If the eruption is huge, the smoke can travel far or there may be an earthquake.
In terms of eruptions in the states themselves, the largest eruption goes to the 1980 eruption of Mount St Helens. The largest eruption to occur on U.S. soil was the 1912 eruption of Novarupta in Alaska. This eruption was an order of magnitude larger than the Mount St Helens eruption, but at the time Alaska was not a state.
No. The last eruption of the Yellowstone volcano was about 70,000 years ago. Its last super eruption was 640,000 years ago.
The Yellowstone caldera is not "overdue" for an eruption. You may have heard that the Yellowstone Caldera erupts regularly every 600,000 years and the last major eruption was 640,000 years ago. In reality the caldera does not erupt regularly and as gone as long as 800,000 years without a major eruption.
No. The last time Yellowstone erupted there were no people around to be affected.
This cannot be predicted. While Yellowstone has produced several eruptions larger than any seen in human history, it has also produced a number of much smaller eruptions.

No. Chances are it would not affect the chances of an eruption.

In most cases, geologists would see signs of an imminent Yellowstone Supervolcano eruption weeks or even months beforehand. A geologist who specializes in volcanos would be a volcanologist, who are more apt to recognize the incoming signals.
