As for why when you socket the item it don't apply the affix I don't know..
As for the all the items you need to roll them..
As for the gems you are using rubies would be best because they add extra damage..
Inside rubies you can not have the base affixes that's the 6 on the main tab you can only have a mystic.
Durability should be 0 for everything unless you want the gem to fall out of the item after you hit something with it and not be reparable ever..
Now why everything is low as you said is because you didn't roll the item..
Since you are so versed in computers I will assume that you read the release history.. Because you have read the release history you will already know how to roll the items for both mystic and root seeds..
