for the weapon i'd go with absorb stamina if you can. with a 2 hander, stamina is needed. for armor pieces it just depends on what you need. with heavy armor i find my encumbrance is an issue until i get the armor perk that makes it not encumber me but the weapons are still heavy so you can carry much. other than boosting/fortifying 2 hand or armor, any elemental resistances always help.
Yeah as Geckoman said. I'd go with a stamina absorb on the weapon if you can. For the armor, I would go with elemental resists since you can't really block elemental damage with a two handed weapon like you can a shield.
