160 gear is still the max.
I don't know if One Tamriel was out before you left, but if it wasn't you are now scaled (like you were in Cyrodiil anyway) and can go anywhere you want on the map.
So if you like questing, you can go through that. You can also run dungeons. All dungeons have a Normal and a Vet mode now, and the pledges can be done in Normal, Vet, or Vet Hard Mode (for extra keys), but the loot drops are the same (just different quality)
There's also an event starting today that gives extra rewards for running a "random" dungeon using the group finder.
