After sending in the I-130, we were just sitting back, waiting for our notice of approval (NOA).
But then my wife was in a US-Expats forum and someone said that they'd sent in both the I-130 and the other forms at the same time, suggesting that we download the DS-230, fill it in and send it in early (although the DS-230 goes to a different address).
After a couple of weeks, we got the NOA and then my wife phoned the consular office to advise them, and got our case number off of them.
Then, about a week after that, she lost the case number, so emailled them again - they replied and advised us of our interview date, with the confirmation arriving in the post a couple of days later.
To snatch a bit of a post from "marsbar" at talk.uk-yankee.com...
You fill out the DS-230. You only fill out Part 1 though. Part 2 goes with you to the interview, and you sign it in front of them. You send off the completeled DS-230 along with the checklist (DS-2001) - - - do you have your police records?
Wherever it asks you for your case number, leave it blank. You don't know it yet, and that's fine.
You'll probably get the DS-230 in the mail in a few weeks, because they won't have known you already sent it in. They are assuming you're doing it the slow way now - but you're not. DO it now to save a few weeks!
So basically, send inthe DS-230 and your DS-2001 to advise that you're ready for the interview and have all the necessary paperwork.
To clarify, we had the following:
Passport (and a FULL COPY - take two, as you may need one for the medical)
Birth Certificates (and copies if you want to keep the originals)
Marriage Certificates (and copies if you want to keep the originals)
Police Certificate (and copies if you want to keep the originals)
copies of your last 3 years US tax returns (I took further copies too)
Affidavit of support - you MUST have one from the petitioner (your spouse), but can have additionals if required.
All affidavits require Proof of assets - we took (along with copies) a letter from our estate agent confirming the value of sale of our house and a copy of our mortgage statement showing how much we owe.

For us, our family size was 4, so the poverty line was $18,400
- 125% = $23000 (about £13,500) Your assets need to cover 5 times this amount for your affidavit of support.
(I am sure that all of the above is correct, from what I remember, but most of my paperwork has now been boxed up ready for shipping - I could open up my brown VISA envelope and check, but ... NO CHANCE!)
