Torch is your friend here. To get the treasure chests on the bottom right side of the map, let one high movement unit light the way with torch, and another high movement unit clear the narrow path. Be prepared with healing items, if you have physic staff, even better. By the time you reach the chests, an enemy thief should already stole the items, and you are just in time to take it back.
For the chest above you, you can either let a flying unit carry a door key and fly up there, or go around the middle. Enemy thieves are not that quick with stealing this chest, so you have a little bit of time to work your way there.

Boss Strategy:
In case you didn't know where he is, he's sitting on the throne. Beware of his Eclipse, which will reduce anyone's HP by half. He's pretty weak physically, so use weapons instead of magic. Pegasus Knights are good aginst him because they have high resistance with a decent attack.
