a jQuery plugin - Want critique

Hey all,

Say a piece of JS i liked and thought I'd have a play myself and see if i could make it into a jQuery plugin.

I used the a boilerplate as a base.

;(function ($, window, document, undefined) {
    var pluginName = "bcToc",
        defaults = {
            contentAreaID: 'content',
			contentLinkClass: 'contentLink',
			addClassToLink: ''
        };
	
    function Plugin( element, options ) {
        this.element 	= element; //create original element object
		this.jele 		= $(element); //create jquery object of element

        this.options 	= $.extend( {}, defaults, options ); //add otpions onto default for full list

        this._defaults 	= defaults;
        this._name 		= pluginName;
		
		this._links 	= $('#' + this._defaults.contentAreaID + ' . ' + this._defaults.contentLinkClass);
		
		this.init();			
    }

    Plugin.prototype = {
        init: function() {
			this.getItems(this.element, this.options);
        },
		getItems: function (el, options){			
			var thisObj = this;			
			$(this._links).each(function(index, element) {
				var newline, 
					title 	= $(this).attr('title'),
					links 	= '#' + $(this).attr('name');
					thisObj.setItems(title, links, thisObj.options.addClassToLink);
			});
		},
		setItems: function(title, links, classes){
			newLine = '<li><a href="' + links +'" class="' + classes + '">' + title + '</a></li>'; 
			this.jele.append(newLine);
		}
    };
	
    $.fn[pluginName] = function ( options ) {
        return this.each(function () {
            if (!$.data(this, "plugin_" + pluginName)) {
                $.data(this, "plugin_" + pluginName, new Plugin( this, options ));
            }
        });
    };

})( jQuery, window, document );

Wonder what improvements i could make or advice for the future.

Feel free to take it and use as you want.

Cheers
