And of course, @Dylan posted this years ago and I've never forgotten it. Very cool:

I finally got to see the international space station fly overhead tonight, flaming quick isn't it, been waiting for a clear night all week
17000mph if i recall correctly.

Just whack your town/city in there and sign up for alerts! You get emails the day before telling you when, where to look, how long and where it stops being visible!!
Eg, the last one I got:
Time: Wed Aug 02 5:33 AM, Visible: 2 min, Max Height: 49°, Appears: 49° above SE, Disappears: 11° above SE
7.66 km/s or 17,134.93 mph
Its exact speed will be dependant upon the height they are flying at but you're right, it's usually around 17k mph (27k km/h)
You are right there!
The closer to earth they are, the faster they go. However, the designed orbit is almost circular, with apogee at 408km and perigee at 401.1km. That being said, they do allow the orbit to decay to assist the likes of Soyuz (and the shuttle, when it flew) to dock with less fuel used. When that happens, the orbit can drop to around 330km. Interestingly, because Falcon 9's CRS is much lighter, they don't have to do this, so they tend to stay at the higher orbit for those missions.

Strange Storm as Wide as Earth Appears on Neptune
PUBLISHED August 4, 2017
Neptune’s wild, windy weather has taken a turn for the worse, with a new storm erupting in a surprising spot near the beautifully blue planet’s equator.
Estimated to stretch roughly as wide as Earth, the young storm system is a big, bright cloud that’s probably raining methane ice into the planet’s interior. In recent images from the Keck Observatory on Mauna Kea, Hawaii, the cloud appeared to brighten between June 26 and July 2, and it was still roiling as recently as July 25.
Though storms have been seen evolving on Neptune before, such a massive storm has never been seen near Neptune’s equator—the planet’s bright stormclouds generally appear to cluster closer to the poles.
“This one is weird, because it’s really big and it’s not dark. It’s bright, and the bright stuff is probably sort of like cirrus clouds on top of a thunderstorm that’s underneath,” says Bryan Butler of the National Radio Astronomy Observatory. “And it seems to be staying steady, for it’s been a month or something now.”
It’s not often that we get to watch tempests evolve on the solar system’s farthest-flung giant planets. Neptune orbits an average of 30 times farther from the sun than Earth, and it has not had a spacecraft visitor since 1989.
Based on the observations we have, it seems that bright, icy wisps of clouds come and go, as do the dark, giant storms that smear the planet’s face. In 1989, the Voyager 2 spacecraft observed a Great Dark Spot—a roundish cyclone—that rivaled Jupiter’s Great Red Spot in size and bested it in windspeed. But by the time the Hubble Space Telescope swiveled to look at the planet in 1994, that spot had vanished. Instead, Hubble observed a smattering of bright clouds in the north.
When UC Berkeley graduate student Ned Molter first saw this massive cloud through Keck’s eyes in June, he and his advisor Imke de Pater thought it might be the same storm Hubble saw 28 years ago.
It wasn’t. Now, the team is working on figuring out how such a humongous cloud emerged, formed, and stayed put near the planet’s equator.
“Since it must have been around for a few weeks at least ... something must hold it together,” de Pater says.
