If you wan't to build a website where users can log in and store their scores, you'll need to learn a web backend language too. I would recommend this Udacity course (https://www.udacity.com/course/developing-scalable-apps-in-j...) since you plan to learn Java anyways.

This would be intimidating at the beginning, but you seem motivated enough to survive it. :)

Overall, I feel like you are on the right track. Building projects/games/websites would lead to better learning.
