Nofollow doesn't stop the page rank leakage, but it doesn't leak as much as a dofollow link either, it's something like half as much.
The best practice would be to just footer index pages that are key pages that you want to have the best SERPs.
While that is the best practice for preserving page rank, it might harm sales. I think that a lot of people have come to expect SOME customer-service oriented links in the footer of a site.
