I am giving you the biggest congratulations ever! First and foremost, according to your description you are definitely working on a lot. So I don't want to overwhelm you with any new information. I think it's best for you to take small chunks at a time like you're doing and I think you are doing great! My only suggestion is for you to rewatch this video and look at what your pinky has a tendency to do. Randomly you will curl your pinky all the way down and almost behind the neck and sometimes it flies off the neck and then sometimes it has a good position. Try to work on gaining control of your pinkie right from the get go in this stage of your playing, and try to move it like how you move your other fingers. All of your fingers should move in the same exact way if that makes sense if it doesn't make sense just let me know and I would be more than happy to elaborate! I am so proud of you!
