If you want a pile of good items including lots of ebony armour and a few bits of glass armour, go to the Redoran Plaza in Vivec. In one of the manors, upstairs there is a room with a lady in it and a key to the Vault in the drawers. If you can steal that key, go to the Redoran Treasury, into the Vaults, and head down to the bottom vault.
Open the door and go in, there'san ordinator in there but if you wait long enough with the door open he'll walk out, and you close the door and start looting. I used the "coc" cheat to relocate all the items to my house because everything's so heavy it would have taken me an hour or so to move it all
Also, if you don't want to wait for the ordinator to leave the room, close the door and taunt him into attacking you and kill him. This way you also get some indoril armour to either sell or decorate your house with (I'm just decorating my house with everything from there, already got enough cash from slaughtering ordinators.)
Also there's an almost full set of glass armour in the Fighters Guild in Ald-Ruhn if you can pick lvl 80 locks (personally, i just made a spell that does Open Lock 100pts).
