Your Answer for Question 1:
Regularity allows for more familiar implementations without many specially-made features. We can make hardware do addition like we do addition. The alternative is simplicity; we do what is easiest for the hardware even though it might be more difficult or cumbersome for humans to understand and carry out.

Your Answer for Question 2:
RegWrite is a signal that indicates whether or not the register will be written to on a given clock cycle. If it is asserted at a clock edge, the register is written to; if not, then no write can take place.

Your Answer for Question 3:
The Add unit is there to calculate the branch-to address. It wouldn't be possible to combine the ALU and the Add unit since the two results must be in two different places when the branch logic is executed.
