The story line quests give high xp as a reward, but unfortunately i have already completed them on my higher level toons. There are a few more daily quests that have xp awards, like the crystal quest in Nordr, the Camilla quest outside Kraken Mines, the Kill-Antee-Quest from Dimitrius and the Karin quest - the last 2 u can get in Kraag tavern.
Sorry no screenshots.
