I found that by adding the following code to extend the jQuery object that you could better integrate the plugin with jQuery itself. This way you can create and alter the FCK Text editor via jQuery.

Example Usage
//create the fck editor
jQuery('#textareaSelector').fck();

//get the value for the instance just created
jQuery('#textareaSelector'). getFckHtml();
// extend $
//##############################
$.extend($.fn, {
getFckHtml: function(){
var editor = FCKeditorAPI.GetInstance($(this).attr('name'));
return editor.GetXHTML(true);
}
});

$.extend($.fn, {
setFckHtml: function(html){
var editor = FCKeditorAPI.GetInstance($(this).attr('name'));
editor.SetHTML(html);
}
});
