If you would like your input fields to show the field title on hover, you can add it in your customizable HTML with [input title="The field name"]. If you would like this to be on a larger number of fields, php may be easier.

Change 554, 555, and 556 to the IDs of the fields that you want to make conditionally read-only.

When you integrate with other plugins, some may expect a format other that the standard yyyy-mm-dd the Formidable uses. In this case, you can add a hidden field to your form, and use custom code to fill it with the date in the format you need.
