Thanks for the info. I had read about that too, and searched the Tirerack website, without any luck before buying my new tires. Just now though, I was able to find the number to call regarding shaving.
All in all, I would have spent $170 for a new Hankook Ventus V12, and I spent $440 for a set of the same size Continental ExtremeContact DW, shipped and mounted (was able to do them myself) after selling the 3 Hankooks. So, I don't feel too badly about it, but will definitely keep the Tirerack info in mind.
After checking the tire circumference calculator, I learned that the stock tire has a circumference of 77.340, while the 245/40/17 has a circumference of 77.651. While this is just over 1/4 inch difference (recommended by Subaru), it should work to get me home if I get a flat.
We can call off the search, I had what I needed the whole time. Thanks.
