Your Answer for Question 1:
Convention: divide registers into 2 classes of registers
 $t0 - $t9: 10 temp registers, not preserved by the callee
 $s0 - $s7: 8 saved registers that are preserved by the callee.


Your Answer for Question 2:
We should eliminate the steps to setting up the stack frame because in non recursive languages, the stack frame can be static since there is only one procedure call at a time. The error we often see in scheme is segmentation fault in which the base cases are not correctly identified. 

Your Answer for Question 3:
The use of registers and the convention of organizing into 2 kinds of registers are quite interesting. With only a small number of registers and memory, MIPS is able to organize lots of variables, procedures and the code itself.
