1) What is the purpose of the ".shp.xml" file?

You can delete the .xml file.
The .xml file contains the dataset's metadata. The metadata is the data about the data, or in other words, a description of the dataset you are using, such as who made the dataset, when it was made, how it is to be used, etc.
This file is completely optional, but make sure you really do not need it before you delete it. To be safe, maybe you can just cut out the file and place it somewhere else, and in case you need it later on you can just copy it into the folder that contains the shapefile.
