Take the stats class and I think you have a very good profile

Are you considering taking the GMAT again? I wouldn't unless I had lots of time but you do have some breathing room since you are applying next year. Your target schools seem very appropriate and I'd aim higher (in the Kellogg range since you want to do luxury goods marketing) if I were you.
I would caution and say that many women coming out of b-school want to go to into this field; it is highly competitive. I might especially focus on schools in NY since it is far easier to get an internship there at a luxury goods brand than from some other schools as they don't typically have dedicated recruiters coming out to the b-schools.
I worked for several luxury goods companies in the past so am pretty familiar with the recruiting process, let me know if you have questions.
