The book "The Art of the Infinite" might be helpful. (Click for a review.) Check your local library.

I can't say why infinity was usefull before calculus, aside from just something to be able to answer the question: What's the largest number? Granted, infinity is not a number, but a mathematical concept. Calculus is all about infinity  the concept of dividing through by conceptual infinities and such.

People didn't invent infinity for no reason  it came with zero! And I can say with most certainty that you see the reasons for zero!
