Welcome to the forum. I have a comment concerning your timeline assumptions.
According to the Visa Bulletin for October 2010, selectees from Asia with case number below 10750 can apply on October 1st as per the 50 days advance notification. Last year (i.e. the visa bulletin for October 2009), that number was only 7200. So the difference is 3550!
I think it is safe to assume that this year, the process would be faster than last year for the same number i.e. 2011AS15xxx should be faster than 2010AS15xxx (by at least 3550 given a comparable processing delay to last year). Combined with the 50 days period (previously discussed in this forum and others), i anticipate that with your number, you may be able to send your package on March 1st 2011 or even Feb. 1st 2011 (which would leave 6-7 months for processing).
