EEA Family Permit, I have all documents but how many of each? Problematic situation that I should disclose?

[Rogue25]

Hello, I have checked here and many other websites for information on the documents that I will need to provide when sending in my application after my biometric appointment. I feel like I pretty much have everything but I am just curious on the specific quantity of documents to provide because I could probably send them hundreds of documents but I am sure that is excessive. Just for some background:

I am American and my wife is Greek and she is currently living in the UK. She has a permanent residence card from the UK as well. I have also studied my Master's degree in the UK from 2015 - 2016.

So just a few questions:

1) My relationship with my partner began August 2011 and we got married in Hawaii December 2017 so we have a pretty hefty amount of photos between that time. My questions are:

• How many photos should I send them?
  What is the best format? (Should I print each photo out individually or put multiple photos on one sheet of 8.5x11in paper)?

2) My wife has several pay slips, invoices, and tax returns from living in England (She has been there since 2012). My question is:

• How much of each individual documentation should I provide?

3) IMPORTANT! Last time I visited the UK (5/1/2017 - 6/8/2017), I was detained at the airport on arrival for some time. The border force officer wanted to look up more information about me to see if my previous flight dates were accurate. He returned to me and first said that the system says I overstayed when I visited 1/21/2017 (During the time I finished my studies, the university notified Home Office that my studies was completed early and so I had to leave within three months, so I DID!). He said this was a mistake which he corrected after I explained that I went home after having my visa was curtailed.

He then accuses me of accepting Government benefits which I have never done. He eventually lets me into the country because apparently the dates from when my benefits kicked in don't match up with the time that I left. He suggested someone stole my identity in the UK using my National Insurance Number so I went through hoops trying to figure it out.

Long story short, I came here and told my story last year and someone suggested that I contact Department of Work and Pensions and this is what they said:

"My investigation into your situation has now been completed. I can confirm that there is no benefit claim associated with either your name or your National Insurance number. I have also checked to ascertain if there is a benefit claim associated with your previous address – again no benefit claim has been made.

Therefore I can say that you do not have a benefit claim of any kind associated with your name or your National Insurance number."

So my question is:
Should I also disclose this information in a letter and send the email that details that there is in fact no claim. The border force officer said I would be flagged in the system as a means to "track and find" the person that may have stolen my identity but I believe this to be untrue. I don't want to accuse anyone but either the border system detected the claim from another person who lived at that address after my stay or the border force officer was just trying to catch potential criminals by lying to them. This whole situation has stressed me out to no end and now everything is dependent on:

What exactly does their border system detect, will this falsely show up during my application and was it a lie and I have nothing to worry about?

Just a reminder, I was never refused entry into the UK.

Help would be greatly appreciated!

Probably should send a copy of the DWP’s letter to clear any potential confusion that may have lingered in their files.

Okay, I'll do that. Should I also write a letter in addition to having the DWP's letter?

Also I answered No to:
"Have you ever been refused entry clearance, leave to enter or leave to remain in uk?
"

My application has already been submitted, will this effect anything? I mean I technically wasn't refused entry clearance.
