This is a great guide to get started. Truly the best way is to dig in and use Google when you get stuck. Terminal is your friend and not your enemy (remember that).
I think this is a great way to introduce yourself to Ubuntu. Another great way to understand Ubuntu specifically is to understand that Ubuntu is a distribution of Linux built on Debian Linux. Linux comes in many 'flavors' and you just need to find what works for you. I am always happy to see new Linux users eager to learn. My advice is to jump in and start playing around. It is not as scary as it seems. Open-source and free is the way to be :)
Here is a new book that just came out and covers 16.04. You can buy a physical copy of it in the link below.
Here is another handbook you can read online for free.
