I guess you can spend some on weapons and armor - but if you do smithing you probably make them yourself, and ebony weapons are standard draugr boss loot once you reach a higher level (not even that high). You can buy houses, training, filled soulgems for enchanting... If you get Hearthfire spend them on building houses.
