I didn't want to hear that kind of BS. I ask a question, so you either answer ACCORDINGLY or NO ANSWER AT ALL!

I do not want to hire a lawyer, I want justice, so I want a lawyer to answer my questions here!

The question about the equipment needed should be addressed to the court's bailiff. Some courts have all the equipment (called an ELMO), and all you have to do is ask. Other courts require you file a motion. Search the internet for your court's local rules. Some courts have no such equipment. Whether or not the document will be admissible in evidence depends on what it is. Some evidence is self-authenticating. Other evidence must be authenticated by testimony of a witness. You have to call the right witness and ask the right questions. Some evidence otherwise inadmissible can be used solely to cross-examine an opposing witness. We can't tell you how to do that without knowing what document you want to introduce into evidence. We all took a course in law school called Evidence and another course called Trial Techniques. Those courses took over a hundred hours. It is impossible to give you all the information you need in an answer here.
