How much of my documented evidence do I legally have to provide to my ex before I request it's submission?

We are both going to be pro se and I have a ton of documented proof of his malicious behavior. I won sole physical last year. My ex filed a Motion Regarding Custody over 6 months ago to attempt to take custody back. He never followed through by scheduling the hearing. I had the court schedule it for him which is in two weeks. I am filing my Response but also want to file a Motion to request sole legal as he has denied me parenting time and sought medical care (including an emergency surgery) without informing me. And now he has cut off all communication with me by not responding to my emails and refuses to give me his phone number. Many complaints to FOC, but they do nothing to enforce my court order. Since last year, my ex has maliciously and intentionally attempted to alienate me from my children. And succeeded with our 13 yr old son. I now fight for my younger two children as my ex has placed them in the middle and lied to many government officials including two judges from two different counties, social workers, counselors and child protective services. I have a ton of documentation to prove every lie. What do I legally have to provide him copies of prior to our hearing since I will request that the documents are entered as evidence? I don't want to make him aware of all of my "big guns." I want to request sole legal custody of the two younger children with as little visitation for him as possible due to the psychological and mental trauma he has caused the children. One is in counseling already. Is there anything else that I will need to file besides my Response to his motion?
