An interesting observation is that you did not state your age, which might shed more light on your potential for progress. Your coach's age is not as consequential as yours.
On the problems you described, like others have commented, practice should take care of many issues.
As for coaches, a stubborn trainee would quickly lose the best coach. Coaches are talented humans and deserve the full trust of a novice trainee. Even an imperfect coach would offer better option than you’re shopping around for a perfect routine.
