It's Good that your shoulder does not dislocate anymore. As far as the clicking sound goes. it probably is because of weakness of the stabilizers and the rubbing of the tendons on each other.
Next problem you mentioned is for the Symmetry.
It's NORMAL HUMAN POSTURE Shoulders are not at symmetry (have a look at anyone). In your case since your left shoulder is lacking exercise since past one month that you used to do. It is Normal that your Left shoulder muscles has gone atrophy (basically weakness), and therefore it appears to be hanging and not symmetrical
