Just out of curiosity, is it okay to use the phrase "and so" in a sentence? Like "Johnathan knew that he had to help the boy asking a question on Jiskha. And so, he did just that, and the boy went on to being the happiest boy on earth."

I just need to know if "and so" is a proper introductory element.

In casual writing, I think "and so" is okay. In more formal writing, I might prefer "therefore", or "as a result", or merely, "so".

In any case, it really isn't necessary at all. The sentence could begin, "He did just that..."
Alright, thanks!
You're welcome. Keep in mind that other tutors/teachers might have a different "take". It used to be that beginning a sentence with a conjunction ("and", "but", etc.) was considered bad grammar. Now it's more acceptable. I still think the "and so" is unnecessary.
