Your Answer for Question 1:
If we do not pipeline the control, then our new datapath would not have any control and it would not know when it should or should not write to the regfile or which function the ALU should perform. The datapath would also keep doing the same thing rather than having the control signals changing. 

Your Answer for Question 2:
The values come fron the write-back stage, the memory stage, and the values fetched in the instruction decode stage.

write-back stage ->
lw $s0, 0($t1)
add $s0, $s0, 1

memory stage ->
add $t0, $t0, 1
sub $t1, $t0, $t1

id stage ->
add $t0, $t1, $t2
sub $t3, $t4, $t5

Your Answer for Question 3:
A bubble is inserted by deasserting all of the control signals. The same bubble would not be inserted over and over again because the following instructions fetch themselves and squeeze the bubble out of the pipeline.
