First off, great summary particularly on the armor and resist balance. I'd just like to add a little more detail behind the reasoning behind the 1 resist: 10 armor ratio.
There's a pretty comprehensive argument here
TL;DR
1) Armor and Resist All (x10) provide the same benefits and...
Not that much. I started doing full act 3 clears as soon as patch 1.03 was deployed and back then 5-10M gold was still worth quite a lot.
Using current item prices, I'd estimate about 20-35M per piece. Not counting the weapons and gems of course.
Yes, it's possible but as a disclaimer, the gear reqs to make it happen are pretty high and therefore expensive. :(
It took a long while and a lot of gold to get there myself but once you're over the gear breakpoint though, it's a more time efficient way to get your paragon up.
