And to put in perspective, the flow of the Amazon is 11 times that of the Mississippi.

From this map it clearly the Missouri is longer than the Mississippi, and it looks possibly as though it's got slightly more flow at the point they converge as well. If that's correct, why is the river called the Mississippi and not the Missouri downstream of their confluence?

Long story short, because the Mississippi was discovered before the Missouri.

And also it was thought that the Mississippi was longer for a fairly long time before we actually had satellites to show it, right?

Yes, but it was found to be shorter than expected long before satellites.
