Hello,
Sorry for delay in reply.
Your GMAT - Your GMAT falls within range of all the schools across world, so your GMAT is not a concern at all. For schools mentioned by you (Kellogg, LBS and Booth), your GMAT will not be a constraint at all.
Since you are 32 right now, you would fall in the bracket of older applicants (do not worry though), so a few points
1) Apply to a few more schools. You can set priorities in place, but keep the bracket of no of schools high. top schools would hardly have 5% (or less then 5%) candidates in this age bracket, but at the same time students applying at this age are also on lower side.
2) Your goals do not sound clear and concrete to me, you will have to work on the same. When you apply as an older candidate, the adcom expects you to have crystal clear career path in your mind (especially short term and medium term). You have time, so work on your goals, this process may take time and patience, but hang on with the task and come out with concrete goals.
3) Your chances to schools such as HBS and Wharton would be slim, but you surely have a decent chance for schools from top 5-10 including Yale, Duke, Cornell. Kellogg would be a bit stretch, but I would encourage you to apply considering you differentiate yourself from typical indian IT male.
4) In terms of improving your profile, I might suggest you to develop a strong EC profile during the remaining months, because you might not have something unique to talk about here.
5) I would also suggest you to decide which region do you want to be a part of post MBA. If you think you can go beyond US, you may apply to INSEAD and IMD as well.
Hope this helps
