For your second question, http://en.wikipedia.org/wiki/Heaviside_step_function has some details.
As for the rest, there are a number of accessible texts on Fourier series or transforms: Tolstov, Fourier Series; James, A student's guide to Fourier transforms; Bracewell, The Fourier Transform and its Applications (out of print), Brigham, The Fast Fourier Transform and its Applications.
While a good teacher can undoubtedly help, mastering course material is largely up to you, and this becomes increasingly true at higher levels of education.
