How to make that google wont follow these two pages:

This is not WordPress specific.
You can also use the wp seo plugin by yoast http://yoast.com/wordpress/seo/ and select no index no follow on the pages you want to block. Also dont worry google cannot see the users account details in products-page/your-account/ it will just see a empty page.
