I am starting up a new project and I am reviewing my best-practices to try to prevent any problems, and also to see what bad habits I have gotten into.

I personally have a different coding style to that. This is one of them. The other is basically an imitation of the style used in backbone.js

var myProgram = (function() {
   var someGlobal, someGlobal2;   

   var subModule1 = (function() {
       ...       

       var init = function() {

       };

       ...

       init();

       return { 
           "someMethod": someMethod,
           ...
       };
   }());

   var OtherSubModule = (function() {
       ...
       var init = function(param) { ... };
       ...
       return { 
           "init": init,
           ...
       };
   }());

   var init = function(param) {
       ...

       OtherSubModule.init({
           "foo": param.foo,
           "bar": param.bar,
           ...
       });
   };


   return { 
       "init": init,
       "somePublic": OtherSubModule.foobar, 
       ...
   }
}());

Depends whether I need to supply a public API to other users, which backbone does a lot better. I prefer to make modules driven by an init function for initial configuration and for the rest completely event driven.

[Edit]

Given the edited question I have a different pattern for this. Each file defines a function on some object in my case it was $.FooBar.plugins

(function() {

    var foo = function() { ... };

    var bar = (function() { ... }());

    myNamespace.plugins["MyPlugin"] = function() {

        ... do stuff
        ... bind to evevnts
    };

}());

Then we use a boot strapper that was something like this :

(function() {

    var needed = function() {
         // Feature detection
    };

    var load = function() { ... };

    var getOptions = function() {
         // Call something on a page by page basis.
    };

    for (var plugin in pluginList) {
         if (needed(plugin)) {
               load(plugin, function() {
                    // get page specific options
                    var options = getOptions();
                    // run plugin
                    myNameSpace.plugins[plugin](options);
                    // If all have been loaded trigger ready handlers
                    if (pluginCurrentCount == pluginCount) {
                         readyTrigger();
                    }
               });
               pluginCount++;
         }
    }

    // start loading plugins after all have been counted
    load.startLoading();

    var readyTrigger = function() {
         // Run all ready handlers
    }

    // Implement your own DOM ready function to run when all plugins
    // have loaded.
    myNameSpace.ready = function(handler) {
         if (isReady) {
             handler();
         } else {
             readyList.push(handler);
         }

    };
}());

That's a lot of gaps and pseudo code but you should get the idea. If it's not obvouis feel to question it.

Then on the page we have something like this

<html>
<head>
  <script type="text/javascript">

    var pageSpecific = {
         "pluginName": {
              "cssClass": "foobar",
              "submitOnEnter": false,
              ...
         },
         ...
    };

  </script>
  <script src="bootstrapper.js" />
  ...
</head>
<body>
  ...
</body>
</html>
