Athens was ruled by first an oligarchy, then a tyranny, giving way in 507 BCE to a limited democracy.
The land battle of Plataia 479 BCE was part of the Persian War 499-449 BCE. The Persian invasion force, having been defeated at sea the previous year at Salamis, was withdraw. Land and sea battles continued on for the next thirty years, with decisive battles at Eurymedon 466 BCE and Cyprus 450 BCE, after which the Persians gave up and agreed to peace.
No, 356 BCE is earlier.
2012 BCE falls within the 21st century BCE. The centuries are counted backward from the year 1 CE, so the 21st century BCE includes the years 2100 BCE to 2001 BCE. Therefore, 2012 BCE is part of that range.
