Gform_field_standard_settings more advanced examples

I am having difficulty with Gform_field_standard_settings.
The example in documentation is very a simplistic example and I wish they provided several different examples...

http://www.gravityhelp.com/documentation/page/Gform_field_standard_settings

I am trying to repurpose this to use a simple input text box but having a difficult time figuring how to prepopulate the box after the user has entered the data. I am also having a difficult time figuring out how to access the entry object and form object from this filter... I tried declaring globals and or passing more then 2 arguments into the function.

add_action("gform_field_standard_settings", "my_marketo_settings", 10, 2);

function my_marketo_settings($position, $form_id){

	if($position == 0) {
	?>
		<li class="marketo_setting field_setting">
				<label for="field_marketo_label">
						<?php _e("Marketo Field Name", "gravityforms"); ?>
						<?php
							gform_tooltip("form_field_marketo_name")
						?>
				</label>
        <input type="text"  id="field_marketo_name" class="fieldwidth-3" onfocus="SetFieldProperty('marketoName', this.value);" value="" size="35"/>
		</li>
	<?php
	}
}

add_action("gform_editor_js", "editor_script");

function editor_script(){
    ?>
    <script type='text/javascript'>

				jQuery.each(fieldSettings, function(index, value) {
					fieldSettings[index] += ", .marketo_setting";
				});

        //binding to the load field settings event to initialize the checkbox
        jQuery(document).bind("gform_load_field_settings", function(event, field, form) {
            jQuery("#field_marketo_name").attr("value", field["marketoName"]);
        });
    </script>
    <?php
}

add_filter('gform_tooltips', 'add_my_marketo_tooltips');

function add_my_marketo_tooltips($tooltips){
   $tooltips["form_field_marketo_name"] = "<h6>Marketo Name</h6>Enter the marketo field name";
   return $tooltips;
}

I was able to find a solution....

It seems the value is appended via javascript and it uses the same input html for each field... So I need to detect the to see if the custom property exisited, and if "undefined" then set value attribute to blank...

add_action("gform_editor_js", "editor_script");
function editor_script(){
    ?>
    <script type='text/javascript'>
				jQuery.each(fieldSettings, function(index, value) {
					fieldSettings[index] += ", .marketo_setting";
				});

				jQuery(document).bind("gform_load_field_settings", function(event, field, form) {

					if (typeof field["marketoName"] !== "undefined") {
						jQuery("#field_marketo_name").attr("value", field["marketoName"]);
					} else {
						jQuery("#field_marketo_name").attr("value", '');
					}

				});

    </script>
    <?php
}
