SEO use rel attributes on all links

We need to use rel attribute for all links that we generate as some of them contain command so we do not want robots to index those.
Guide to all possible values for rel are here: http://www.w3schools.com/TAgs/att_a_rel.asp

We want to use:
1. rel="nofollow" for all commands, cart, checkout, selfcare
2. rel="bookmark" for all links leading to products or sku
3. rel="search" for all search navigation links

Additionally need to ensure meta tags for no index of pages: https://developers.google.com/webmasters/control-crawl-index/docs/robots_meta_tag?csw=1
<meta name="robots" content="noindex" />
This is for: cart, checkout, selfcare and return urls from PG's
