The GMAT is only one small part of the application and it is actually only cost of entry. It can keep you out, but it won't get you in. 740 is above average for Columbia (and no need to worry about your AWA).
I would highly advise you to focus on the rest of your application. Unfortunately you are part of an overrepresented demographic (Indian engineers) which means that you are competing against many candidates with similar profiles. Thus focus your attention on standing out! CPG experience is already a distinguishing factor. Three things (among others) on which to focus:
1) What makes you you? Think about your profile. What do you enjoy doing? What do you do in your spare time? How do you define yourself? As part of an overrepresented demographic you will need to make your case for entry by showing how you are different from others with similar backgrounds. As long as your GMAT is above average, an increase in score will make little - if any - difference.
2) Think about your goals and how they link to your past.
3) Think about fit and WHY you want to go to these schools. The programs you chose are VERY focused on ensuring you will fit into their culture. Each has a very distinct personality - but they all want to know you want to attend their school. Spend time attending online webinars, going to alumnae events, and talking to current students. The more you know about the schools, the better you will be able to demonstrate your fit. (The schools you picked are very different from one another).
Scores will only take you so far. Get some sleep
- and focus on developing your overall strategy / getting to know the schools better.

p.s. In addition to being an MBA Admissions Counselor I am a CBS alumna. The unique thing about CBS is that it was almost every attendee's first choice. The AdCom is very good at determining who will be a good fit at Columbia (as seen by their essay questions).
