By far, the BEST XP at low levels would be the Gnoll Fang quest in Qeynos / Halas. Killing Blackburrow Gnolls who drop the occasional fang gets you XP plus it's fun. The REAL XP shows up when you turn these fangs in. I leveled up twice during one turn in. It's a pain to get over to the Qeynos area for you but well worth it.
