quest turn in/ power leveling advice

[Ashur]

So my brother is level 30 and my SK is level 9. I want to catch up with him asap. My SK is a troll so I get the double whammy of exp penalty. I was thinking of focusing on quest turn ins such as the lightstones in the gypsy camp in NK. Being an evil race, what turn in quests should I be focusing on pre-level 30. I will try to farm pp with my bard to use a power leveler during the levels where turn ins aren't viable. Any additional insight or advice appreciated. Thanks
