Your Answer for Question 1:
regularity and simplicity allows many different hardware units that need to use the same function to be able to all send inputs in the same manner to the same unit.  an example of this is the ALU.

Your Answer for Question 2:
the regwrite signal signals for an input into the register file to be written into a register.
