You might try welding gloves or fireplace gloves. (fireplace gloves tend to be longer, and might go up to your elbow).
They're typically made of suede, with an insulated lining. I use them instead of pot holders, but they also come in handy when I'm doing large amounts of grilling (once a year, for our departmental picnic, cooking for a couple hundred people).
The fireplace gloves also come in handy when camping, as you can reach in to move logs if you're quick about it. The only issue is that too long of exposure to hot, dry heat will cause them to harden up and lose their insulating properties. I have to get a new pair every few years or so because of the way I use them.
I also have some really heavy duty rubber gloves that I got more as a joke -- I'm not sure if they're for haz-mat purposes, or what, but they come in handy for when I have to deal with hot but wet things. I've also used them when dealing with cleaning out the fridge at work that had gotten pretty scary (it was near a conference room, and people using the conference room would leave stuff in there and forget about it). I've seen similar gloves, maybe not quite as thick, though, at a restaurant supply store near heavy rubber aprons for the people doing the washing up.
And, if those still don't fit your preferences, you can find silicone potholders ... they've got good grip, and you should be able to roll it into a cone around your piping bag.
It seems the best thing to do is to have a sealed container with little air in it.
CO2 has proven to be useful, but its presence is not as important as sealing.
So, if you want to preserve cotton candy, my experimental results show that a sealed container is preferred. I obtained a conservation of 24 hours, but probably it will least 48h or even more.
EDIT: Well, sealing seems to work pretty well, but I have to report a pair of failure...
2 out 5 packages did not preserve the cotton candy for more than 24 hours, while the remaining did. On the plus side, the first experimental sealed package preserved cotton candy for more than a week.

What you need, my good man, is a candy fork.
Basically it's a two-tined fork with incredibly thin tines. Dip, lift, allow excess to drip off, place on parchment (you will get a tiny 'foot' but this is normal).
unless you're talking about absolutely perfect spheres? to my knowledge this is not doable by hand, you will need industrial machinery. and the two hemispheres method will leave you with a seam.
i have heard one solution for the tiny hole left by a thin skewer is another tiny dab of chocolate and a quick blast with a hair dryer to smooth out any imperfections, but i have never tried it myself.
