Neat plan! I'll add a tangent, that if the material on Thermopylae intrigues you, there's a really good trilogy of historical novels by Helena Schrader about Leonidas and archaic Sparta that tries to lay out the best of our current knowledge (which is very different from what scholars thought about Sparta even a few decades ago...it's taken a long time to peel back all the appropriation on top of the fact that most of our sources are Athenian).
