Is a sill seal necessary on a concrete slab foundation with no crawl space?  And if so, is a termite-shield copper flashing with a polyethylene membrane backing adequate as a sill seal too?

Right, it basically serves those two purposes.  Of course, a rubber membrane would probably be better for separating the wood from concrete, and the sealing is only effective if the concrete is reasonably flat.
