Putch is correct- you may only take one magical item from each list (i.e. "Magic Armour," "Magic Weapons," "Arcane Items," etc.) and magical shields, helms, and suits of armor all fall in the same list. You may take a mundane shield with a suit of magical armor; just make sure that you read the armor description carefully, as many of the descriptions specifically say something like "Grants a 2+ armor save that may not be improved by any other means."
