Your Answer for Question 1:
The simplicity and regularity of the instruction set makes implementing it in hardware easier. This is because the execution of the instruction classes are so similar, with the actions performed being largely the same. In this way, we can keep our hardware simple as well.

Your Answer for Question 2:
The RegWrite signal is asserted so that a write into a register can occur on the clock edge. Otherwise, the data would always be written into the register at the clock edge regardless of whether we wanted the data written or not. 

Your Answer for Question 3:
The purpose of the Add unit is used to increment the PC to the next instruction. It would not be possible, since we always need to add, the ALU would need to be wired to always perform the add function, and would not be able to compute the other ALU functions.
