Yes, daedric ruins are the ones with all the stone and the pointy bits and oval-shaped entrances - they have daedra (atronachs, daedroth, dremora, etc) outside them. Dwemer ruins are the ones that are more metallic with turrets and bridges and circular entrances. They have dwemer monsters (centurions etc) inside them.
Try using some resist fire/frost/shock potions, spells or items with atronachs. They help quite a bit.
I'm pretty sure the yellow book of riddles is important for a temple quest that you get from the temple guy at Molag Mar [img]smile.gif[/img]
