1. The rules state on page 13:
1. Find the Barbarian settlements within
2 spaces of your cities, even accross Sea
spaces (no crossing unrevealed regions).
2. Of these, the settlement with the most
Barbarians attacks the closest of your
Note that it is only "your cities" that are affected. The barbarians can only attack the player who drew the event. Therefore you can manage your advance to avoid triggering a barbarian when you don't want it.
2. From the same rule reference on page 13 shown above, note the words "even across Sea spaces"
3 Player trades are discussed on Page 14:
During your turn, you may trade with other players. You may
also trade with a player during that player’s turn. You may trade
(at whatever cost you can agree on):
• Action cards
• Objective cards
• Mood tokens
• Culture tokens
Trade deals with an immediate transaction of the above items
must be fulfilled. Verbal agreements of a diplomatic/political
kind, as well as loans and transactions to happen at a later time,
are not enforced by the game. Only the players’ conscience and
goals determine the validity of such agreements.

I love the box art as it really does capture, in my mind, a Clash of 2 very different cultures.
