sed / awk / grep on files in directory

Hello:
I need some help please. I need a ksh script that will perform some rather basic sed/awk grep commands.

I have a directory full of .txt files. Each file in this directory needs to undergo a treatment.
(learned from earlier EE posting)

1. sed -e 's/~/~\n/g' $file1 > $file1.$$

I'm interested in lines starting with "W12" within these files.  When I grep for that pattern in each .txt file, it produces STANDARDIZED output like this. (Delimiter will always be a '*' and position is fixed.)

W12*CL**18****VN*4921427~
W12*CL**3****VN*4921537~
W12*CL**4****VN*4931037~
W12*CS**2****VN*5057600~
W12*CS**5****VN*5057604~

2. I'd like to see the filename _AND_ line number where the grep match took place
3. Also need to count the # of times 'CL' and 'CS' appear in that output shown above.
4. Need to put a tab between the 5th and 6th char in the 7 digit integer shown in lines above.
5. Need to e-mail the ultimate output to a list of users

Thank you very much.

#matched lines
grep -n ^W12 $file1.$$


CL_count=`grep -n ^W12 $file1.$$ | grep CL | wc -l`
CS_count=`grep -n ^W12 $file1.$$ | grep CS | wc -l`

#4. Need to put a tab between the 5th and 6th char in the 7 digit integer shown in lines above.
grep -n ^W12 $file1.$$ | sed 's/\(.*\*\)\(.....\)\(..\)/\1\2\t\3/'   > final_out.txt

#5. Need to e-mail the ultimate output to a list of users
mutt -a final_out.txt  -s "the output" receiver@domain.com
