As a quick note from what you had written, we normally do not recommend using letters of recommendations from professors. If you are not sure whether a recommender is appropriate, think about the types of questions they will have to answer. These questions are often frequently linked to your leadership skills, your performance on teams, communication skills, ethics, and more. A professor is usually not in a position to comment on these traits.
For the schools you have listed, your GMAT score is strong, but for the more competitive programs you will need to differentiate your candidacy through your work experience or outside activities. Programs are going to be looking for applicants with leadership experience and for individuals who have made an impact. These need to be emphasized on your application. Your personal essays and recommendations are going to be critical.
As a note, if it was your first ever time taking the GMAT test and you believe you can improve your score by 40+ points, you may want to consider the test again. Business schools will only consider your highest score, as it is self-reported on your application.
I hope this was of help.
