I'm with Eric. I'm mostly self-taught, myself. Early on, I got a copy of John L. Fierer's "Cabinetmaking and Millwork". It's an industiral-arts text that used? to be popular in vocational school woodworking classes. Covers a lot of the basics fairly well, but is oriented toward power-tool woodworking, in a career-preparation sort of way for those who were headed into the furniture industry. Still, I find myself referring to it from time to time to refresh my memory on something.
There's a world of other books out there - Tage Frid's books are good, oriented more toward fine furniture woodworking. Spend a bit of time at a bookstore or library, glance through some books, pick the ones that speak to you at this point in time. You can always go back and get others as your skill level improves.
But, most of all, get some boards and make some sawdust! It's fun!
