I wouldn't worry about it. The SERPS of your "Contact Us" page isn't really important is it? I'd consider not displaying empty category pages though, or excluding spiders from them via your robots file. Concentrate on getting people landing on pages that convert sales.

Spiders only look at content when weighing the uniqueness of any given page, so the template (HTML, CSS Javascript etc) is ignored.
