No. I can confirm that all of the items you listed are being worked on though.
Right now, the priority is with responding to notable issues raised with 1.1.0 - especially the save-load issues that some users are experiencing. Some time after that I would expect the next beta release. Similarly, I would not expect the discussion of new content, be it DLC or otherwise, before the current goals (or the new content itself) are completed / closer to completion.
Depends on the trait, but traits in general have a broad application in the game ranging from NPC relationship generation over execution consequences to various decision making (voting (policies, war/peace, etc), sacking a city or not) etc.
