Have you looked at the NetApp University? You'll need a login, however there is alot of free WBT available, which is also mapped to what you want to learn, including a "New to NetApp", please see link: https://learningcenter.netapp.com/content/public/production/learning_maps/customer/lm_customer_t2.html
Have a strart there and you'll likely have some more specific questions.

Sorry, forgot to mention you do indeed have the manuals...http://docs.netapp.com/ontap-9/index.jsp
I would start with the Introduction and concepts section (http://docs.netapp.com/ontap-9/topic/com.netapp.nav.ic/home.html?cp=1) and you do not need an account!
