IIRC Lion has a pattern for worsted socks on their site (for Lion Wool-ease of course, but I'm sure you could use whatever's close in weight).
Also I just got "Getting Started Knitting Socks" by Ann Budd. It has basic patterns for different gauges from 8 sts/in to I believe 5... so you could pick the one that works with your preferred needle/yarn combo.
"Knit Socks!" by Betsy McCarthy also has some worsted patterns.
