Achilles didn't really have a quest, but he joined the Greeks in battle to get Helen of Troy back to her husband Menelaus. Since his mother was a river goddess, he was able to get armour crafted by Hephaestus himself. Although he was the bravest soldier in the ranks of Agamemnon, he was killed by Paris of Troy. The Greek gods and goddesses were divided in this matter, like Poseidon and Aphrodite were with the Trojans, while Athena and Hephaestus aided the Greeks.
Achilles' armor was given to him by Hephaestus, the god of blacksmiths and fire. After the death of Patroclus, Achilles mourned and sought new armor to replace his damaged gear. Hephaestus crafted a magnificent set of armor, including the iconic shield, which was described in great detail in Homer's "Iliad."
Legend has it that he suicided after shaming himself while temporarily deranged, after Odysseus won a competition between them for the dead Achilles' armour. Following the chronology of his forbears, he would have been dead by the time of the Trojan War. The bards introduced him into their story of the Trojan War to have yet another great hero.
Odysseus and Telamonium Ajax compete for the armour; it is eventually given to Odysseus. Odysseus ends up giving the armour to Achilles' son, Neoptolemus.
