There is no need to do all this manually. As Makarius mentioned, this is
prepared as an component and components are documented in the system manual:

Add the line

   init_component "$SOME_DIR/ProofGeneral-4.2-2"

to your $ISABELLE_HOME_USER/etc/settings file, where $SOME_DIR refers to
the directory where you want to store the extension. ($USER_HOME/contrib
might be a good value for that, as that is the directory the repository
version stores its components by default).

Then execute

    isabelle components -a

to automatically install the missing component. Afterwards,

    isabelle emacs

should give you a Proof General, provided you have an appropriate emacs
installation around.
