[Avodah] berachos 7a; schena and nevuah???

[Harvey Benton]

Berachos 7a says moshe requested that the scheina reside only with yisrael. 
1. was this request before the episode of bilaam? 2. does this request include prophecy? E.g are the scheina and nevua related? 
Does one need one for the other??
 3. Can we learn out kal v'chomer that if the shechina resides only with israel, then for sure nevuah does??? HB
