At your level, I suspect you'll have a tough time at Shangri-la. You may be able to slowly take on the monsters in the instance, but the boss will probably crush you without help from a higher-leveled player.
Have you looked for quests in Aoich? There should be quests available there for Cherry Lake and in the Dark Moon Castle after you get a few more levels. I believe you're at the right level for Snowfield quests from Elias too.
