This perl script should do the trick:

----------- munch.pl ----------
#!/usr/bin/perl -ne
chomp;                         #strip newline
($n,$u)=split(/\s+/);          #split fields on one or more whitespace
$u=~s/^..(.).*(...)$/m$1$2/;   #repl 2nd field with 'm',3rd char, last 3 chars
print "useradd -c \"$n\" $u\n";#print out the shell command
-------------------------------

Use it like this:

munch.pl < FILENAME
