You probably learned a level of Bless or Heaven's Gift. You can also check with Blake in Ars Magicana and Corinna or Mpenzak in Verdistis for spell books.
If you quick save before running your mouse over an item/chest/merchant or hitting the alt key, you can identify the item or trade with the merchant, then quick load to get different stats or inventory. This can be done repeatedly to get the best stats or specific bonuses on an item (save after finding good candidates) or looking for specific items (such as spell books or charms) from merchants.
If you are done all of the quests, you can gather all the loot you want to take with you and hit the gong (it is a one-way trip). You can buy spell books from the merchant in the wastelands, as well.
