I was reading a tread about how little air holes appear in drywall mud. There were multiple suggestions of adding a little ivory soap and water to drywall mud to make it as smooth as a baby's butt. How much soap to water to mud would all you pros out there recommend?

Ideally this should be screwed/anchored into a joist for maximum support. However, if you really want to use a drywall anchor, you should use a toggle bolt or a ceiling anchor. Instead of just screwing into the wall, these expand to several times their size which gives you a good hold, especially when the force is pulling directly down. 10lbs might be pushing it though, it will depend on the thickness of your drywall and the overall condition. The worst case is you just have to patch the hole and repaint; drywall is pretty forgiving like that!
Take a paint stir stick from a home improvement center, break it into pieces that will fit behind the patch hole, and pop in a screw to hold it in place, on the side away from the tile. It doesn't have to be rock solid, it's purpose is to keep the drywall patch in place long enough for the compound to dry. Once the patch is in place (liberally buttered with compound) and dry, you can remove the screw holding the stick in place- the stick may drop off into the wall, but that's no great problem. Patch the screw hole, and you're set.

It has been a while since is did it but it did have an impact on the air bubbles.
How much soap ? Very little, much less than you think.
I have done the soap, maybe a half tablespoon for a gallon or two of mud, but i do not use any water.
I remember adding too much the first time and it was a little thin/loose, hard to work with.
I used generic dish soap.
You can always add more but you can not take it out. ( I have cut this board twice and it is still too short )
