For harvesting I can say that there will be tools and clothing. There will be upgrades of these and the items you use for harvesting will effect your harvesting outcome a great deal. It won't be the only factor, but better gear will make for better harvesting for sure.
Also, you may get harvesting clothing and tools in a variety of compelling ways. You won't start out with everything you need to harvest all resources effectively, but you will start out being able to harvest something. - 19 November 2005
