One more - after the second 'know'.

I wouldn't put any commas at all. I'd write "I want to know need (1) to know how all these things work" if I was(2) quoting something someone said, but if I were(2) expressing my own thoughts I'd write "I need to know how all these things work".
(1) Emphasis seems necessary, as I can't easily imagine someone saying this without emphasizing the "need".
(2) It seems a little odd switching from "was" to "were" here, but "was" seems right to me the first time, as it's expressing a possibility, whereas "were" seems better the second time, as it's counterfactual. Opinions?

Both are subjunctive, even if you might have actually written the quoted material previously, since that event would have been incidental to now saying how you would punctuate the words and why, if you so chose to write those words.

I would have inserted a second comma after "need to know," but otherwise, I would have phrased the sentence as, "I want to know and need to know how all these things work," or "I want and need to know how all these things work."
