I checked that wiki's MediaWiki:Common.js - the scripts are installed properly, and here is where you can see the "My Tools" menu alongside the buttons themselves, at the bottom with the toolbar.

About renaming files, yes it should be possible - simply put the full name of the file to be renamed e.g. File:Example.png and the new name such as File:Example2.png.
