What do you mean "best method to retrieve resources"?
A login page is just like any other JSP. You "retrieve" the resources by coding their URLs in HTML tags. It's better if those URLs are not secured URLS (since you're not secured yourself yet!), and you can have problems when the page or page resources invoke complex platforms such as JSF or Struts. But other than that, it's business as usual.
Customer surveys are for companies who didn't pay proper attention to begin with.
