Your Answer for Question 1:
MIPS Has 2 classes of registers: those that need to be saved on a procedure call by callee ($t0-$t9) & those, that must be preserved ($s0-$s1).
Thus, inside procedure can use temp registers without need to save them first. Spilling is required only if temporary registers are not enough.

Your Answer for Question 2:
We could alliminate allocation of frames on stack - each procedure's frame is statically allocated, since only one invocation of the procedure can be active at the time. 

Problem is infinite recursion: if it is not allowed in the language, then it won't arise.

Your Answer for Question 3:
Still not clear what needs to be saved 
a)on call by caller
b)on call by calee
c)on return from callee to caller
