Planet13, I seriously doubt you're going to be penalized for implementing standard breadcrumb navigation such as is found at the top of this page. It's pretty much universally considered a good idea and in most cases improves both usability and SEO. Indeed, Google explicitly recommends it in their SEO guide:
Ensure more convenience for users by using ‘breadcrumb lists’
A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page (1). Many breadcrumbs have the most general page (usually the root page) as the first, left-most link and list the more specific sections out to the right.
