Team game questions: When does a team hold a continent?

Suppose I'm in a triples game: Does ONE specific team member need to hold an entire continent to be eligible for the continent bonus, or does a mix of players on the same team also count as holding that continent?
I understand I can deploy on my own territories as well as team mate's territories; same for fortifications right?
If I kill a team-mate: Do I get his cards?
What is the order of play? (Assuming it's a sequential game) ? I suppose after a team member of one team finishes his turn it's then the turn from the next player on the other team?
Anything else I need to know to win team games?
