With the 2000 pages I sent in a cover letter explaining all of our communication, my mom also communicated with her every few weeks on Skype and I sent that in as well. Knowing that it was a short courtship I tried to include as much as possible, Facebook posts, Facebook messages, western union receipts. Even if she doesn't need the money send her a bit every month if you can and keep all the receipts. I also made another trip about 6 months after the wedding and sent an update to Manila with additional photos, chat logs, western union receipts, Facebook posts, etc. I also got her a credit card on my account and had her do a bit of shopping every week using the credit card and included that in the 2nd package I sent directly to Manila. Added her as a life insurance beneficiary through my work plan and included proof of that.
I don't think it was as well organized as others but basically I included everything I could and wrote a cover letter explaining how often we communicated, how we met, why I married her with such a short courtship and exactly what we did during the 3 weeks I was there for the marriage as well as the 2nd trip. I didn't want to leave any questions unanswered and tried to be as thorough as possible. The cover letter from both the initial submission and the 2nd one i sent to Manila was about 4 or 5 pages.
As far as how it was organized I would follow this page, they did a much better job than i did:
