Went to District Court today. Every time I go there I feel a little dumb, because all that stuff is "foreign" to me. I had to ask some questions several times just to clarify things.
Now I have a few answers regarding my particular case:
1) They don't require to put numbers in the beginning of each paragraph. They told me this "As long as they can read it you are fine. There are no numbers in the template, so you don't have to use numbers".
2) They don't use Appearance form.
3) I have to make a copy or each Summon and a copy of each Complaint and serve each defendant.
4) There are several ways to serve a defendant. When defendant is a government I can use a "green receipts". That means use USPS to deliver my letter to a defendant. There are other ways, but I won't describe it here, because I believe that USPS Green Receipts are more than fine in this case.
5) Besides 8 defendants I have also serve Attorney General of Delaware.
6) If I won't get all 8 receipts that will be a problem. Typically they should provide me a Green Receipt within a few days. If not I can try to resubmit my letter.
7) Then after each defendant is served they will have 60 days to reply.
Now I have to:
1) Fix some items in Cover Sheet
2) Double check addresses of each defendant
3) Create a summon for each defendant
4) Make a copy of complaint for each defendant
5) Make a copy of complaint for District Court
6) Make a copy of summon and complaint for Attorney General of Delaware
7) Print all copies of summons and complaints and go to the District Court.
8) Pay fee, get everything stamped and then go to USPS to send all that stuff to all defendants and Attorney General or Delaware.
9) Get all green receipts and return to the District Court.
10) Then probably wait another 60 days. After that I don't know yet.
I have two question:
1) That addresses listed in addresses_law_suit.doc file - are they absolutely correct?
Yes (since all my defendants received it 
).
But you can still Google to double check, dude.
2) In the cover sheet there is a section "VI. Cause of action". Unfortunately I don't know how to fill it out. In District Court they told me there should be some particular U.S.C., but I don't know how exactly to fill both fields of that section: "Cite the US Civil Statute under which you are filing" and "Brief description of cause".
Check "462"
Cause of action: "U.S.C. 1447(b)"
Brief description: "No decision made after 120 days since the initial N-400 interview"
