Is this 100% argon gas, or does it also have nitrogen?

The can says it contains a "custom blend of pure nitrogen (N2), carbon dioxide (CO2) and argon (AR)" It works very well.

How does it work and do you need a special stopper?

Looks like the inert gases displace oxygen to prevent oxidation. You do need a wine stopper to keep the inert gas in and additional oxygen out. Doesn't appear to need to be a special stopper though.

Is preservation performance affected if I lay the bottle on a rack after closing? I have a chiller which doesn't accommodate standing bottles.

No. It doesn't need a thick layer of gas to keep the wine protected as long as it stays still, but you might give it just a little more if it's on its side.

Can someone tell me why simply pouring the wine into a smaller bottle, or half bottle, filling to the brim, wouldn't accomplish the same thing?

It would accomplish the exact same thing...though you are the most industrious win drinker I have ever heard of. This is meant to be a quick and easy way to keep a partially full/empty bottle of preserved in its original bottle. There is always more than one way to skin a cat....this is just one of the easier ways.
