Good ideas, though these guards should be very rare. The Dwarves' skill in smithing has declined over the years, and these suits of dragon-fire-resistant armor should be rare by the Third Age.

Also, it should give resistance nearly complete resistance to normal fire, while giving a much more limited defense against dragonfire. Because the Dwarves could resist dragonfire only because they both wore masks and were, well, Dwarves, who are naturally hardy (Incredibly hardy) and pretty much completely fire-resistant on their own.
