Note that factor four is the vestige of the Frye ruling, so, while Frye is no longer the standard, it remains one of the tests of such evidence. This probably sounds more imposing than it is. I also used my poster system. Even when the opposing attorney successfully objects to your using it, you still are likely to get some credit from the jury for trying, Strategically, I think it hurts the opposing counsel more than it helps to keep that demonstration from the eyes of the jury because the jury is likely to feel that, as the triers of fact, it should be up to them to see all the evidence. They will often view that attorney as manipulative and unfair, rather than as the champion of justice.
Literature is another thing entirely.
Generally, you won't be able to walk into court with a stack of papers that opposing counsel has not previously been privy to. The important caveat here is to know that literature well. And, to a lesser degree, know the other literature written by those authors. It is always amusing to remind myself that I'm the only person in this case who really has nothing major at stake. I'm being paid for my time regardless of the outcome.
