10 digit of the VIN is the year. This is true of all cars.
G is 86
H is 87
J is 88
K is 89
etc
Correct. This is the best way to verify model year. Look at your VIN.

After October the vehicle is considered a next year model. Example: 7-10 manufactured date is a 2010 vehicle, 9-10 is a 2011 vehicle.
This isn't really true for most cars, and not true at all for the Supra. Most Toyotas sold in North America during the Supra's time period had the changeover in August. Looking at your post now, it appears in your second sentence you are also referring to August, not October, since October is the 10th month of the year.
Even so, these days model year changeovers happen all throughout the calendar year, even when a new model is not being introduced. If you want to know your model year, look at your VIN. Alternatively you could check with someone versed in specific knowledge about your model of car, but the first one is easier.
