Here is a pretty good tutorial (I have not yet tried it)
http://www.tata-tatao.to/knit/e-index.html I also have in my "to do" list that I want to try before putting up an article, How to knit two socks at once and I did buy from
www.lacis.com the portuguese hook needles that have a sort of crochet hook on one end and a point on the other that is suppose to make knitting a sock super fast. I was told that these needles were used way back in history and that the portuguese still use them today for lace making.
