The folks at EverQuest II have published an overview of the EQII economy, which has been written with with new players in mind.
"Things can get expensive in Norrath, and sometimes a new adventurer can have trouble trying to make their way in the world. The guide below is intended to help those just getting started get on the road to riches.
Spoils of the Hunt
Perhaps the quickest way to start making money in EQII is by taking quests and hunting NPC's. Quest rewards vary, but usually include some coin and often a loot item or two, such as armor, jewelry, or weapons. Hunting rewards are quite similar; some NPC's drop money, some drop loot, and some drop both.
Winning coin and item upgrades is great, but selling the loot and rewards that you don't need will bring in even more money. You won't necessarily be rolling in plat at the start, but for buying lower-level upgrades to spells, armor, and weapons, it's a no-cost way to put a little jingle in your coin purse. And if you're fulfilling quests by killing monsters, you're getting double the bang for your buck; experience points plus money and loot."
