LaTeX

Doing my best to learn LaTeX. I've been meaning to for quite some time, but hadn't gotten around to it. Now that Nick and I are starting to look into the business of selling printed copies of people's journals to them, I figure I should learn how to do some quality typesetting. (that and I need to buy a two- to three-thousand dollar color laser printer....) Any recommendations on either sources to learn LaTeX (books or websites) or good laser color printers? (HP 4500 DN looks good....)
