Here's an example from  
https://extensions.gnome.org/extension/141/lame-extensions-manager/

const mgr =  
imports.ui.extensionSystem.extensions["ExtManager ilikepepper tk"];
const extManager = new mgr.manager.ExtManager;

Here's an example from  
https://extensions.gnome.org/extension/59/status-title-bar/
        tracker.connect('notify::focus-app', Lang.bind(this, this._sync));

> (3) How can I catch the event "a new window was just created"?

you can use 'window-added' event.
sample from workspace.js file:
            this._windowAddedId =  
this.metaWorkspace.connect('window-added',
                                                             Lang.bind(this,  
this._windowAdded));
for more examples:
$ grep -n window-added /usr/share/gnome-shell/js/ui/*

> (4) and "a window was just destroyed" ?

you can use 'window-removed' event.
sample from workspace.js file:
            this._windowRemovedId =  
this.metaWorkspace.connect('window-removed',
                                                               Lang.bind(this,  
this._windowRemoved));
for more examples:
$ grep -n window-removed /usr/share/gnome-shell/js/ui/*
