Your Answer for Question 1:
If we didn't pipeline the control then our  whole processwor would not be able to                  run at a faster speed.  If we did not pipeline the datapath then our throughput would decrease because we aren't speeding up things like beq.                                                                                                                                                                                                                                                                                                                                                                                                                                 

Your Answer for Question 2:
One of the values is the output from the register file,  The other possible values are from the ALU or the write buffer.

00 = get value from register file
01 = get value forwarded from data memory
10 = get value from ALU result

Your Answer for Question 3:
If we deassert all the controls we pretty much get a nop instruction and that makes it act like a stall or a bubble.  Since time will progress our older instructions, data dependecys should be able to go away over time.
