I know stuff about what you are trying to do but I've never read any books on it, I just learned it all by making shit for the last 15 years. PCB design is mostly just a big logic puzzle unless you are dealing with very high frequencies, just make sure the high current traces are wide enough and as short as possible etc.

pic related, a custom arduino board I've made a couple dozen of with an onboard RTC and EEPROM that is 33% smaller than a standard duemilanove board.
