Marriage based green card

I was wondering what documents should gather for this adjustment of status on my spouse.

Additionally, I did have an arrest on my record 24 years ago (im the citizen by the way) It was for drugs but it was dismissed and I’ve had no other issues. Should I gather anything on me showing my rehabilitation etc.? I’m a licensed medical professional with a business etc so I’ve for plenty of evidence I can submit if needed on me.

Thank you.
