Namespacing method?

[Aaron Zeckoski]

I am trying to figure out the best practice for JS namespacing and
there is a ton of conflicting information out there.

I have sorta settled on one of these:
1) From some of the websites on namespacing
var AZ = function($) {
	var private_var;
	function private_method() {
		// do stuff here
	}
	return {
		initDeleteList : function(deleteUrlPrefix, deleteClass, itemPrefix,
itemDeletePrefix) {
			// do stuff here
		},
		method_2 : function() {
			// do stuff here
		}
	};
}(jQuery);

2) From looking at the Fluid stuff as an example
var AZ = AZ || {};
(function($){
	var private_var;
	function private_method() {
		// do stuff here
	}
	AZ.initDeleteList = function(deleteUrlPrefix, deleteClass,
itemPrefix, itemDeletePrefix) {
		// do stuff here
	}
	AZ.method_2 = function() {
		// do stuff here
	}
)}(jQuery);

3) ??????????

Any recommendations on best practices?
Is there a webpage I should be looking at?
