Inventory items, non-inventory items and multi currency

My organization has a new requirement to price items in foreign currencies. Is it possible to use multi currency to price non inventory items? Currently, we do not have the Inventory module enabled. If it is not possible to price the non-inventory items, is it possible to price these items in foreign currency using the inventory module? Any feed back is greatly appreciated. Thanks.

 

Additionally, is it possible to use statical accounts in conjunction with $0 items to record weights and volumes?
