Are the breadcrumbs going to be static or dynamic? In other words some of your pages probably have multiple ways to drill down to them. Are you going to display dynamically generated breadcrumb links that change based on how the user drilled down into the site or are you hard coding navigation links that never change?
Either way breadcrumb links tend to be devalued by Google since they are not embedded within the content. This is not to say they are useless just that they tend to be worth less than a link embedded in a relevant keyword rich article.
