- use furnace filters to 'clean' incoming air

Good luck with that. That was my plan when I painted my car in the garage several year ago. I found that hanging the plastic sheeting was a pain, and didn't really accomplish much. I just covered up the garage items closest to the car.
Wetting the floor, in concept, sounded like a good idea, but in practice was not and I stopped doing it. When you wet the floor, everything gets wet, the airhose for the spraygun, etc. Its easy to splash water on the car while you are painting, obviously a bad thing, when you have the floor wet and water everywhere.
I'd recommend just washing down the floor before you start, and letting it dry.
I found that even in the garage, dust is not really a problem. The biggest problem I found was keeping the supply air dry and clean - compressing air creates a lot of moisture, and that can be disasterous to the paint.
You are going to get a little dust and imperfections in the paint when you paint in your garage. They KEY, though, is to put enough paint on the car so that you can do a pretty aggressive color sand. That will take care of any dust, imperfections, etc.
There is a danger of putting too much paint on, but for a garage job, its better to have a little too much than a little too little. You can and will be color sanding and doing a lot of polishing - you need to have enough material on the car to handle that.
