Don't even mess with bone chips. The market is so overflooded (and necros generally farm their own anyways) that it's pretty dang tough to unload even a 20stack at peak hours. You are better off hitting up the Nybright Sisters in Lesser Faydark or Crushbone / Unrest / Befallen / Upperguk etc.. depending on where you are centrally located. You will do plenty fine for cash just killing things..
Best advice is to use the wiki and figure out what spells you'll want and need right away and which you can wait on for a few levels till your cash supply overflows.
(example: Dance of the Fireflies and Ward Summoned.. not so necessary at early levels. Skin like Rock and Healing and Shield of Brambles and Snare, however.. very necessary..)
And of course, never hesitate to ask higher level priest classes how they survived at lower levels. Many will often toss you cash or a lowbie item/weapon or two just to be left alone. Or even know of a place at your level they hunted at which brought them untold riches. Knowledge is power.
