any help in MIPS?

[Dewey1040]

I honestly don't fully know where to start with this program but this is what i have

Write a MIPS program which read one line at a time from console. For each line that you read, print two lines on the console: echo print of the line and types of individual characters on the line.
The character types are defined below:

Characters Type Comment
0 1 .. 9 1 Digits
A B .. Z a b .. z 2 Letters
* + - / 3 Operators
. ( ) , : 4 Delimiters
b 5 blank
# 6 End of the Line

For example, when a line of the input below

THISLOOP: LWU R2, 3 #

the output from the program will be like

THISLOOP: LWU R2, 3 #
222222224 222 2141 6

getline: 
	la	$a0, st_prompt		# Prompt to enter a new line
	li	$v0, 4
	syscall

	la	$a0, inBuf		# read a new line
	li	$a1, 80	
	li	$v0, 8
	syscall

	jr	$ra

	.data
inBuf:	.space	80
st_prompt:	.asciiz	"Enter a new input line. \n"


	.data

	.word '6', 1 
	.word '7', 1 
	.word '8', 1 
	.word '9', 1 

	.word ':', 4

After working on this project for 4 hours i finally understand input and output in mips... i couldnt replicate code on a piece of paper but i understand how it works, but this is my code so far, how would i implement the part of the program that prints out the individual type of character? I first have to access each individual character and then change that character into its type... any help once again would be greatly appreciated, I will be working on this throughout the night and probably tomorrow... here is my new and improved code... i just re did my program and took out the stuff i dont understand.

.data
Prompt: .asciiz "\n Please insert a string: "
Buffer: .space 60
Bye:	.asciiz "\n **** Adios Amigo - Have a good day****"
		.globl main
		.text
main:
		li $v0, 4 			# system call code for Print String
		la $a0, Prompt 		# load address of prompt into $a0
		syscall 			# print the prompt message
		li $v0, 8 			# system call code Read String
		la $a0, Buffer 		# $a0 is a pointer to an input buffer
		li $a1, 60 			# specifies the maximum length of input buffer
		syscall 			# read a string and store it into the buffer
		li $v0, 4 			# system call code for Print String
		la $a0, Buffer 		# load address of msg. into $a0
		syscall 			# print the string

End: 	li $v0, 4	 		# system call code for Print String
		la $a0, Bye 		# load address of msg. into $a0
		syscall 			# print the string
		li $v0, 10 			# terminate program run and
		syscall 			# return control to system
