Well there are some great sock patterns at
www.knitty.com and you might also like to get Elizabeth Zimmermann's Knitting Workbook, her Woodman's Socks are knitted in worsted.IMO Elizabeth Zimmermann's books are all essentials anyhow, I'm always knitting her designs! The Knitter's Almanac has some nice sock patterns too and the refootable sock is gone into in detail in Knitting Around. These books are all by the same author.
If I spot a pattern for a good thick sock I'll post it here.
