OK, well pushing out your left shoulder blade I am not sure if you mean making it wing, or if you have trouble making it rotate (or abduct) away from the body. As I have not seen your back but the same for you, prone T's, Y's, W's, L's, and H's to start things off and then maybe move on to something a little harder. You just need overall scapular stability to start. No remember, if your left shoulder is jacked up, its not that weird that the opposite side pelvis is going to be pulled up towards it. All of that **** is almost kind of connected. If look at the way the muscle fibers of the glute run and the same for the muscles around the shoulder you would see that if the lats werent there it would look like one big X on your back. But one issue usually spawns from another with these cases.
For your Hips, yoga draw ins, which look very simplistic will be hard for you, because I am willing to bet that the majority of the muscles in your lower abs probably arent working properly but I cant see that from that angle but its probable. Also Glute med/max activation such as glute bridges would help here.

THose are very simple, helpful articles from some very smart people. IN part 2 pay special attention to the static lunges as those should be great for you. THis is tough to just do through the internet but that stuff should help you and get you started off. I hope thta helped. You will be surprised on how just doing some of those things in your warm up or at the end of your workout will make vast improvements over time. Let me know if you need anything else.
