You are right that your GMAT score is on the low side for the schools you are targeting. It is closer to the average for some, but it is low for Chicago. I think it is helpful that you have good grades in a tough, quantitative major as well as analytical work on the job. These things will help your case, but you might find it worthwhile to take the GMAT one more time to get your score up at least 20 points.
What will make the difference for you is how well you put together your overall application package. If you present a compelling case and have a solid rationale for your MBA, then it can get you a positive decision (even with a 660) at one or more of the schools. You will also want to visit these schools and try to make a personal connection with someone in the admissions office. If you put the effort in, I think you might be surprised at your results.
Best of luck,

Once I take a breather and work on the other parts of my application, I may re-attack that beast again
With the current 660, out of my target schools, which are reasonable for me? And do you have any recommendations as to what other schools I should consider for strategy/management consulting?
Out of the schools you list, you probably have the best chance at Georgetown with a 660, but that is not to say you should not apply to the others. In trying to identify other programs, I would look at the placement reports to determine which schools tend to place a good number in consulting and are in a metro area with large consulting offices. You should be competitive for most schools in the top 40.
Best of luck,
