If you want to learn piano i would recommend This book and This book they are older books now and they say its for children but they are still good. They teach hand positions as well as a little sight reading, both will give you a good starting point to learning to play piano.

In regards to the video, you need to sort out your seating arrangements because the keyboard looks a little high, and maybe change the chair to one without wheels (some people may disagree with that but personally i don't like playing on wheeled chairs). Also try not too sway as much when you're playing, this can be a bad habit to get into which can make reading music later on difficult.

For someone who's only been playing two weeks you're doing okay, just needs some more practice :)
