Answer

There were a couple things wrong here:

needed to change js.src assignment to: js.src="https://connect.facebook.net/en_US/all.js";
Facebook no longer supports JS SDK calls made from a local file, the script has to be run on a file with an http:// or https:// URI, as per this bug report on Facebook. I will need to upload the file to a web server, change the canvas URL accordingly, and retest.

Question 2

I'm trying to run the first example from the documentation of the Facebook JS SDK. I created a new app, created a blank document called "facebookTest.html", pasted in the code from the example, and plugged in the new app's App ID. Code as follows:

<html>
<head>
<title>Login with facebook</title>
<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    // init the FB JS SDK
    FB.init({
      appId      : 'my app ID', // App ID from the App Dashboard
      status     : true, // check the login status upon init?
      cookie     : true, // set sessions cookies to allow your server to access the session?
      xfbml      : true  // parse XFBML tags on this page?
    });

    // Additional initialization code such as adding Event Listeners goes here

  };

  // Load the SDK's source Asynchronously
  // Note that the debug version is being actively developed and might 
  // contain some type checks that are overly strict. 
  // Please report such bugs using the bugs tool.
  (function(d, debug){
     var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement('script'); js.id = id; js.async = true;
     js.src = document.location.protocol+"//connect.facebook.net/en_US/all" + (debug ? "/debug" : "") + ".js";
     ref.parentNode.insertBefore(js, ref);
   }(document, /*debug*/ false));
</script>

When I load the page, on the Javascript console I get the following error message:

Failed to load resource

What am I doing wrong?

EDIT: When I add document.location.protocol before the "//connect.facebook.net/...", as suggested here, the screen stays blank, and the console shows the following:

GET file://connect.facebook.net/en_US/all.js

Is that all this code is supposed to do? Or is it still failing?
