S.H.
I've had excellent luck repainting furniture thru the years. The key is to thoroughly & properly sand it, wipe it down with a tack cloth, & then resand it until it's a smooth surface. You do not have to remove the old paint, you just simply have to have a good surface to bond onto.
I prefer enamel paint for repainting furniture, but have been known to use wall paint for quickie projects. I also think your idea for brainstorming with the staff at Lowes/Home D.....is a great starting point! Good Luck & have fun....
