Minyan.
“Do you bring food or buy on the road? (even if there is no kosher restaurants you can always find plenty of Kosher food at a grocery store with the OU on it)…”
Bring and buy OU when needed.
“What happens if you have to go out to dinner with a client and there is no Kosher restaurants around?”
I don’t understand the question. Going to a non-kosher restaurant is not an option.

No.
