As soon as you get an amulet with paralyse (Amulet of Admonishment, for example), you can go to the ghost gate and find two people with a full set of glass armor, minus the helm. Paralyse and kill them both for a set of light armor if you're skilled in it and some mega cash (if you know how to work that scamp in Caldera). For your constant effect enchanting needs, you can go to Azura's shrine on the coast in the southeast and complete her quest to get Azura's Star, the grand soul gem that never gets used up. Also, you can get the spell Summon Golden Saint from one of the Telvanni towers, either tel branora or tel mora, IIRC. Of course, the CE enchantment stuff should be persued late in the game...

Edit:

Also, the jug of stuff that removes intellegance and gives you strength for like 50secs is usefull in two ways: Drink it and you're strong as an ox drink enough of it to reduce your intellegence to 0, and when it wears off, you'll have all your MP back
