I recommend Ann Budd's book, Getting Started Knitting Socks. It's shows you everything you need to know about knitting socks, includes patterns for socks from fingering weight yarn through worsted, gives very basic patterns for children through women and men's socks, and then gives more elaborate stitches and patterns to use once your more experienced. It's the only sock book/patterns I've used so far.
The book also tells you how to use 4 DPN's or 5 DPN's and 1 or 2 circular needles. Also has a really good lesson on the Kitchener stitch for the toe.
Good luck with those socks!
