When laying out an analog board, keep inputs and outputs seperated. Be aware of capacitive effects on high impedance lines. You should know what a guard ring is, and how to use it. Ground runs should go to a common point as far as possible to avoid cross-coupling. Be aware of special requirements of ICs, look up the data sheets.
Digital layout is less fussy if the speed is low, but still pay attention to ground runs and use plenty of power line bypassing. Speeds above 100 mHz should use transmission line techniques.
