Lost City, Fishing Contest, Fremmy Trials, Tree Gnome Village, Druidic Ritual, Priest in Peril, and Waterfall Quest are all great starts. Most of them give you access to good training areas and help you get around a lot better in the member worlds. Keep in mind that if you don't have the sufficient magic level to teleport to some member areas, you can use the trading boats to charter a boat to either Port Khazard, Port Sarim, Catherberry, and one other place, for a price.
