The spiral manga is called Uzumaki. It's by Junji Ito, a madman horror manga writer who is essentially a genre unto himself and Uzumaki ends gloriously. There are a bunch of relatively cheap but sumptuous hardcover releases of his various series. You should start collecting them before they go out of print and become super expensive.
