The Beyond Divinity Strategy Guide lists all of the set and unique items, but I don't think anyone has compiled a list just about where to get each item. There are no bonuses for completing a set, and the names of set and unique items change when you move to the next act, so there is not much point in collecting set pieces if they are not better than the equipment you are using at the time.

Embellish increases the value of an item to sell to traders. Gold isn't really a problem in the game though, so there are probably better places to spend your skill points.

The crystals are similar, except they can be removed or swapped around. Click on the crystal bag while it is in a character's inventory, and a window will open for the bag. You can drag and drop crystals into or out of the crystal bag window.
