dont ever wear prot and armor combined, you dont get any of the bonusses of a full set then..
At low lvls (57-) i'd say armor or prot.. as a pure str you can go garment later.. its good for grinding in caves
When doing str, dont put any stat points in int.. You DONT want to make a str hybrid char.. believe me.. im lvl 80 str hybrid glavier and pure builds lvl 72 are a problem for me
