Your Answer for Question 1:
Comments - they serve the enligthen the user on the purpose of the code, and...
this one is an attempted educated guess - variable/structure declarations; the compiler would simply allocate space on the stack for the desired amount rather than decrypting what int num means. 

Your Answer for Question 2:
Having read ahead, I know of the addi instruction that can be used to add a integer to a variable (in this case 1)
addi k, k, 1

but a long, unnecessary convoluted way could be done using (assuming here that k > 0)

add k, k, $t0 (k = k + 1)

Your Answer for Question 3:
Understanding machine instructions is cool.
