Battle of Mycale from http://www.encyclopedia4u.com/b/battle-of-mycale.html:

In the spring of 479 BC various Ionian cities began the process of revolting against their Persian rulers. This did not go well at all, and soon they were forced to turn to the Greek mainland for help. A meeting was called in Athens, and ambassadors from several Ionian cities, Athens and Sparta met in the early summer. The meeting did not impress the commander of the Persian forces in Thessaly, Mardonius, so he sent terms to Athens demanding that they stay neutral. When they refused the Spartan delegation started for home to prepare for war. Meanwhile Mardonius' forces soon reached Athens, but the citizens had already retreated to nearby Salamis. Thinking the Athenians are ready to surrender, Mardonius again sent them terms, and was again refused.

While the Spartans prepared for war, eventually mustering a force of 5,000 and another 35,000 allies, a delegation from Samos arrived in Sparta asking for help. The Greek fleet of 110 ships set sail from Delos under the command of Leotychides, a Spartan.

The Battle

Realizing generally what was going on, the Persians disarmed the Samians and sent their ememies, the Milesians, to guard the roads to the rear. Meanwhile the Greeks unloaded their ships and formed up for combat. As usual the Spartans occupied the right wing, placing the Athenians on the left. The Athenians, walking along the beach, found a herald's scepter and thought that it is a divine sign, signifying that the other Greeks had been victorious on the mainland. They then charged forward to the attack alone, and after a short battle the Persians, led by Arta�ntes, were forced to retreat to the fort they had constructed further inland. The Athenians chased them and captured the fort as well. The Persian survivors fled, only to find that the Milesian rear-guard had turned against them as well, and few survived to eventually reach Sardis.

When the Spartans arrived the Persian camp was looted and their beached ships destroyed. Returning to Samos they then discussed their next moves. The Spartans proposed the evacuate the cities of the Ionian Greeks and bring the population to the Greek mainland, as they did not consider it worth their trouble to defend the Ionians everytime they were attacked. The Athenians, however, objected to losing their colonies, and accepted the Ionian Greeks in a league against Persia.

Some notes:

Psiloi were either Peltasts, or Archers, or Slingers or Hamippoi.

Peltasts were carrying a light, usually wicker shield in the shape of a half moon called "Pelte". They were javelin throwers.

Archers carried a similar kind of shield. Sometimes no shield at all.

Slingers would throw rocks or lead balls. Usually no shield.

Hamippoi were light infantry that fought along with cavalry. Similar arms as the Peltasts.

All of the above carried swords as part of their equipment.

In the triremes there were standard 10 Hoplites as marines plus a few officers. There could be some more if the marine crew was unexperienced in sea battled and they wanted to "beef up" their defence. I'm not aware of oarsmen throwing spears! Perhaps if the two ships would be entangled and immobilized they would also help (they were free citizens not slaves).

The Athenian Hoplites like that: . The rest with whatever they could grasp

It wasn't a real land battle between foot soldiers. It was more of a mess...

But you're right. We can't find any sources that give us details so we must deduct this information from previous experience.
