I didn't know you sprayed cars for a living. Now I know you know how to spray paint! With the right paint and gun you'll do an awesome job. Latex with a cheap gun is tough, they tend to spit, clog, or [censored] out. Trust me I've been down that road. Also latex paint on furniture is not that durable, oil is better.
I hear you about hazardous paint, have you considered an oil base trim paint like Satin Impervo? It will spray a lot better than latex will, once dry the paint isn't a problem unless someone was to try and ingest it, and that would hold true for latex as well. Thin it with mineral spirits, clean the gun with mineral spirits. Bring the furniture to the shop and do it if possible, the smell will stink out your house.
You can also take the piece outside and use spray bombs to prime and paint it with good results too.
