Has the Earth's rotation slowed any since man has been able to precisely measure it such as with an atomic clock?

Yes it has - fairly recently, there was an extra second added to one day to put the clocks back in sequence with the Earth's rotation. The most recent occurrence was Dec 31, 2008.

It is a more accurate atomic clock that uses caesium atom frequency to measure time.
What is the highest part of the earths atmosphere?
The highest part of the earths atmosphere is called the Exosphere. The main gases within the Earth's exosphere are the lightest gases, mainly hydrogen, with some helium, carbon dioxide, and atomic oxygen near the exobase. The exosphere is the last layer before outer space. Since there is no clear boundary between outer space and the exosphere, the exosphere is sometimes considered a part of outer space.
