I think the best suggestion, and I'm sure others will agree is to wander around and familiarize yourself with the surroundings. Talking to members in game (remember to use Role Play!) is a good way to gain help in starting. Try asking some NPC's (non playable characters) for quests. You can recognise these by their cyan names when you move your mouse over them. Just click on them and type /say May I have a quest? Sometimes they will have a quest and sometimes they don't, but you should be able to find one. For your troubles of completing the quests, you will be rewarded with either items, gias or both.
Hope that helps!
