Monsters are not very nicely designed (as far as i explored), but they have a variety of names and colors, making your life easier on your hunts.
Almost all NPs will help you with tips, rumors, quests at some point. Major NPCs will give you a series of quests to complete and reward you accordingly.
By the way.... you can have an infinite number of quests in your quest log. Major quests and storyline quest sremain when you log. Secondary quests dissapear when you log - so complete them asap - or keep notes from where you get them.

Crafting system is huge. I havent try to complete anything yet, but you get many options - and is advised to specialize in something (especially if you operate inside a guild).

Keep in mind that is info is based on close beta testing - open beta will be in the end od 2007 (or so i have been told in the game). By that time all characters will be deleted and we will start anew.

More features: you can fly, have a pet, create guild.
PvP, or Guild vs Guild I know not... most players are still low to create guild and we still explore the game, not wasting ourselfes into pvp situations.

Final note: domo gold game is based on cooperation and teaming. Most major quests will demand of you to have a team to complete them. So, train your social skills and get yourself a nice team :)
