Your Answer for Question 1:
To avoid saving and restoring a register whose value is never used, which might happens with a temporary register, MIPS offers:
10 temporary registers ($t0-$t9) that are not preserved by the called and 8 saved registers ($s0-$s7) that must be preserved on a procedure call. 
This reduces register spilling. 

Your Answer for Question 2:
Honestly, I am not sure of my answer. If you eliminated recursion, it would be like not allowing a procedure to call a procedure because in essence that is what it is. So I do not see how we could eliminate procedure call steps if we were forbidded from using recursion. My understanding of $fp is weak but my guess is that you would eliminate use of that. 

Your Answer for Question 3:
Talk more about register spilling, pls?
