What they could do for gear when they raise the CP cap and that is going to happen, is allow 9 trait crafter to raise gear level of gear to the max level using materials, tempers, etc.
Artifacts - I don't know what they are, but these icons have been there since launch.
Probably the Daedric Artifacts that were obtainable in beta. I'm not 100% certain, but I think Artifact001 was the icon for Auriel's Bow in beta.
For those of you who aren't aware of this, a number of Daedric Artifacts were available as quest rewards during the betas. They were replaced with mundane quest rewards on live.
