Creating a New Field

So I have "successfully" created a new field; however, none of the properties or the advanced input areas appear (as I would like to use some of the default ones). How do I 'enable' them?

Here's my attempt so far: http://pastebin.com/Kgf195d2

Thanks Alex. I've incorporated this; however, this adds a placement input area to OTHER fields, but not the newly created custom field, TOS.

Here's the newly added code from the previous pastebin:

add_action( "gform_editor_js", "my_gform_editor_js" );
function my_gform_editor_js(){
?>

<script type='text/javascript'>
	//adding setting to fields of type "text"
	fieldSettings["textarea"] += ", .tos_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_tos").val(field["tos"]);
	});
</script>

<?php
}

New pastebin: http://pastebin.com/iDxYWPbY

Is there a way to add a conditional. What I am trying to do is to create an advanced version of the Paragraph Text. And this is a big stumbling block for me. In essence I want to add an input text box to the Settings, but everything else should be the same.

Now, when I test the Field Size, it is not resizing appropriately. Isn't this accurate?

// Adds the input area to the external side
add_action( "gform_field_input" , "wps_tos_field_input", 10, 5 );
function wps_tos_field_input ( $input, $field, $value, $lead_id, $form_id ){
	//print_r($field);

    if ( $field["type"] == "tos" ) {
		$max_chars = "";
		if(!IS_ADMIN && !empty($field["maxLength"]) && is_numeric($field["maxLength"]))
			$max_chars = self::get_counter_script($form_id, $field_id, $field["maxLength"]);

		$input_name = $form_id .'_' . $field["id"];
		$tabindex = GFCommon::get_tabindex();
		return sprintf("<div class='ginput_container'><textarea name='input_%s' id='%s' class='textarea %s' $tabindex rows='10' cols='50'>%s</textarea></div>{$max_chars}", $field["id"], 'tos-'.$field['id'] , $field["type"] . ' ' . esc_attr($field['cssClass']) , esc_html($value));

    }

    return $input;
}
