Several question about CR1 Interview

[Renegade 11]

Guys, I need some clarification and an advice.

1) We are a gay couple, my husbands (Petitioner)  family (sisters) is aware of our marriage, and supports him. His elder sister is our co sponsor. However my family (Brother and father) don't know anything, and honestly I don't want to tell them, first of all, they're not gonna support us, and second my father is old now, and I really don't want to disappoint him during his last years. So what should I tell during the interview, will that fact be a problem?

2) Any advice on how to correctly arrange my paperwork? Can anyone explain, how it works during the interview. If I understand right, I will submit everything to someone, then it will be handed to CO for a review. So basically, he will review it THEN will talk to me?
Is a photo album with our pictures with dates a good idea? 

3) Should I make a copy of everything that I have, or I will need only originals?

Sorry for a bad English. Im so nervous already :/

Answers:

1. If you are asked, you tell the truth, your circumstances are what they are.  If you are not asked about it, then there is no need to volunteer that information.
2. There is no "one way" to arrange paperwork.  Just know what you have and where it so you can hand it over if asked for.  Everything you submitted thus far is already part of a file that a CO will work off of for the interview.  Don't bother bringing a photo album, if a CO wants to see pictures, an album will be too big to pass through the space in the window that is used for exchanging documents.
3. Up to you.  You've already submitted photocopies of the civil documents so all they need is the original document which will be returned to you.
