If you are running a local Galaxy, the full path to datasets is noted on the "info" page, found by clicking on the circled "i" icon between the disc and blue re-run button.
You can click on the pencil icon (top upper right corner) and rename the user labels any time you want, unless the file is being processed. In that case, wait until it is done, then change. Changing the Galaxy internal name of the file is not recommended, but is probably possible. However, expect the unexpected if you attempt this, as the changes would not be easy for us to support.
To let you know, you may find the the galaxy-...@bx.psu.edu mailing list better for technical local Galaxy questions going forward.
