Profile Evaluation - Chinese/750 top schools within reach?

Hi,
Thanks in advance for the feedback.
Here’s my info:

Male/30/Chinese citizen
BS in Accounting from a top Chinese university
GPA: 83/100 – which I’d say is a solid B equivalent
GMAT: 750 (51Q/40V/5AWA)
Experience – 4.5 years auditing in Big 4 firm; 4 years finance controller in large multi-national company, most of that time in managerial positions (1 year of that in Japan, managing team of 4 Japanese finance managers)
Extracurricular – minimal extracurricular involvement during undergrad – but should be taken in context of Chinese undergrad experience in late 90’s when extracurricular were still fairly nonexistent
Short term goals: corporate finance position in US headquarters of multi-national company
Long term goal: China/Asia CFO for multi-national company

Schools: Wharton, Harvard, Chicago, Columbia, NYU, Yale, Duke, UCLA (safety?)

NOTE: Unfortunately the earliest TOEFL exam I could register for is in late January which is past most of the second round admission deadlines. I plan on submitting all my other materials by the second round deadline but fear that without the TOEFL score my application won’t be considered until the third round.

Also my one ‘worry factor’ is my GPA from college. Should I write an ‘optional statement’ explaining this?

And of course I'm worried about my age, that I may be too old.

Thanks
