You seem determined to practice, practice, practice and expect to go out and have major improvements when you go out to the course. You need to start playing more regularly on a course and take your lumps. Course management, controlling your emotions, hitting a shot under pressure are things you need to learn also. Get past your embarassment for a bad shot or bad round. Golfers know what that is all about and think nothing of it.

Everthing you are doing, books, videos, lessons should get you to a point one day where you know how a golf swing should work and you can begin building a swing with that knowledge. Good luck and go out an play some courses. That is what it is all about.
