Sirclueless,
I think I see where you are going with this. Keep in mind that Alfresco provides a framework for the creation of your own website. This framework currently address forms, versioning, workflow, etc.
If you are looking for a site navigation component, you would need to architect and build one to suit your needs. I do happen to know that Alfresco will release their website Alfresco.com which does have a dynamic navigation component. You could also ask the Alfresco community for examples of what they've built as well.
As far as link management, there is not currently (at least from what I've seen) any automated way to ensure that your links work. Each form page will need to be linked to other pages, or the nav in order to appear on the site.
Does this help?
