I use IPC-SM-782 (Surface Mount Design and Land Pattern Standard) from www.ipc.org. I am not a member but can but publications from them at non-member prices. IPC-SM-782 does not have all IC footprints but has many standard parts.
Another resource (for IC footprints) is Philips Integrated Circuits Packages (Data Handbook IC26)- free from http://www-us2.semiconductors.philips.com/ (somewhere on their website).

I don't really want to wade through a bunch of technical stuff to derive all of this myself and I certainly don't want to trust a priori the patterns that come with Protel or any other product. It's really annoying when part manufacturers don't provide these footprints, assuming they are common knowledge.
