This all looks unnecessarily complicated. I had really bad posture for most of my life and I fixed it with two things: deadlifts and cable rows. After the major muscular weaknesses are corrected (and those two exercises will correct them), it's just a matter of habit correction- stand while you work, walk with your stomach tight and shoulders back, don't let yourself slouch when you sit, etc.
This ain't rocket science. You don't need to spend an hour a day with 10 different exercises. You can fix the muscular weaknesses in 30 minutes, once a week.
