(going by EQlive experience): You can start killing wisps at about level 8, and the greater lightstones can be turned in for a concordance of research which sells for 10p, as opposed to selling the GLS for 5p. My casters always funded their 12~16 spell costs off of willowsisps. They're very common in north karana, west commonlands, and the Island ships dock at in Erud's Crossing.
I forget the exact level, but somewhere around 20~24 there are two static treants in south karana that respawn in either one or two minutes each, and drop considerable wealth in coins and great staffs. I remember seeing drops like 10 gold, 100+silver, etc, so it's rather heavy, but still profitable.
Highkeep guards drop fine steel weapons, and there are merchants in that zone that don't care if you kill the guards. I did that on my necro off and on from my upper 20s until I started killing bards and nobles in my 40s and 50s (right when they nerfed the xp on live).
In the 50s you can easily kill guards in cities like felwithe and oggok.
As you can tell, my necro didn't really care about faction. Your druid friend certainly won't appreciate any of those suggestions, but if you haven't killed a treant you're not a real necro
