I currently have a Daedric Curiass and Daedric Greaves and all my other armor is Grand Madness Armor (all armor is non-magical)
I have completed the main quest line.
I have Shivering Isles and all the DLC.
I am level 21 and have 100 heavy armor, 100 blunt and 100 armorer.

Given this, where should I be looking to complete my set of Daedric armor (or for that matter where can I look for Daedric weapons, especially axes). Or should I be wearing something else instead? (I cant get Perfect Madness armor until level 23)

Also, what should I be doing/focusing on to help level up now that I have 100 in those 3 skills?
