Suggest that you copy and paste content from the word document here (unless it's too big) or attach it as a pure textfile. People might hesitate to open a word-file they don't know anything about.
# 3  
Code:
 
previous_word=
cat your_file |
while read word rest_of_line ; do
  print_word=$word
  if [ "$print_word" = "$previous_word" ]; then
    print_word="\t"
  fi
  print "$print_word $rest_of_line"
  previous_word=$word
done

# 4  
Code:
while(<DATA>){
	my @tmp = split(" ",$_,2);
	if($.==1){
		$key=$tmp[0];
		print;
	}
	else{
		if(/$key/i){
			$tmp[0]=sprintf ' ' x length($tmp[0]);
			print join " ",@tmp;
		}
		else{
			$key=$tmp[0];
			print;
		}
	}
}
