For the birth certificate you should get a bilingual birth certificate from civil status organization in abasseya it comes in both Arabic and English language 
No need for a translated copy cause it will be issued in both the languages
 

All of this!!!!
 
OP you definitely should not have had a celebration or party or anything that would resemble a wedding 
Hopefully it works out for you, but if not be prepared for a real wedding and a CR1

Your Lawyer was wrong in advising you to send pictures with a family gathering. I don't know what the overall picture of the gathering suggestions but from the questions you received from your call from the embassy I suspect they see it "maybe" as a wedding celebration. Keep in mind this is only my speculation. You did do a smart thing my correcting her on the "husband" reference as I think that was the path she was heading down.
 
There have been may cases that what you see as a "party" to what the CO sees as a possible "wedding". I would hate to see you come all this way and get denied because of an innocent picture. Here are some examples and from there you'll need to make your own decision. If you want more information than in the upper right corner of this page is a search box. Use the words "marriage ceremony" and you will have more examples. http://www.visajourney.com/forums/topic/641345-k-1-visa-wedding-ceremony/

I don't think they will see your private messages or posts
It's all about making sure that you're not involved in something bad 
They check your social media history what you posted and your interests 
 
And all they care about is making sure of two things
You really have a genuine love
And also that you're not a terrorist
Other than that you don't have to worry
 
And btw i filled out my DS 160 a week ago they ask only about your user name no password
