As far as health oriented goes:
1.) Buy a double cartridge respirator, these cost $15-25 depending on where you go. Make sure the respirator says it's made for paint use, or that it can filter organic solvents.
2.) Buy some protective eyewear, goggles or safety glasses, to protect your eyes.
3.) If you spray indoors, buy a spray booth that has a good CFM rating. I'd say at least 200 CFM should do it for airbrush use.
4.) Don't get any lacquer thinner or paints on your hands, if you do wash it off immediately. Wear medical gloves if you have to.
If you follow the above steps you can use lacquer paints without any trouble to your health.
