Cornell is a tough school but you are, IIRC, below average among applicants applying to med school out of Cornell. Likewise, your MCAT is a little below avg among Cornell undergrads. About 70% of white applicants with your stats get admitted so you aren't alone if after this cycle you are without a med school.
If this is your first cycle, I'd suggest preparing like crazy and retaking the MCAT in April. Then plan to reapply during the first week of June 2010 if you have managed at least a 34 on the MCAT. Find something (f/t job in research or in a hospital or outpatient setting) to do to support yourself during the year off.
Alternately, take a two year gap. Take some additional natural science courses in 2010-11 to show that you have what it takes to succeed in medical school. This could be undergrad courses, a masters in bio or chem, or a special masters program. Your goal should be a 4.0 gpa, particularly if you are trading down in prestige from Ivy League to state university (regardless of the real difficulty of the coursework the name/prestige is all that an adcom thinks about). Then reapply in June 2011. (If you felt that you needed it, you could retake the MCAT in April 2011). Work during the second year or finish up the academic work need for a degree.
