The engines can determine which links are part of the page template (top navigation, breadcrumbs,left navigation, footer, sidebar widgets, etc.) There's nothing you can do really about those links other than not blatently over optimizing things like the home link with your home page's targeted keyword phrase... use HOME. Those links are going to appear on most if not all of your pages, so those pages linked to in the template are going to have lots of inbound internal links with the same link text. The engines understand that.
However, you do have choices for other links to those pages and other pages on your site that appear in the non-templated portion of the page (generally contextual links and links from widgets that appear in a limited number of places on the site). On a typical site, you should not over use such types of links. And these links should have varied link text including "noisey" link text like "click here", "here", "learn more", etc.
If you find yourself adding a link from PAGE A to PAGE B simply because PAGE A mentions in passing some keyword phrase that is being targeted by PAGE B, DO NOT DO IT! The ONLY purpose for such links is optimization.
However, if PAGE A mentions something that PAGE B specifically addresses and provides further detail that would be useful to a reader of PAGE A's content then by all means link to PAGE B from A. That link is good for your user... AND the search engines.
This is one difference between optimized and over-optimized sites.
Use a little common sense.
