Starting out I would farm bone chips outside Kaladim, loot everything and sell it. Turn bone chips in once you stop getting exp from the decaying skeletons and other slightly higher level mobs outside Kaladim. Sell all the armor rewards from the bone chip quest. Should set you up pretty well. After that head to crushbone.
Aside from that, just don't buy spells you don't need. After eye balling the chanter spell list, that's probably at least half you don't need right away.
