Nathan, always look for documentation such as datasheets and apnotes. Print it out, read it, highlight the good stuff, mark down the settings you use for your SFRs.

Don't limit yourself to those from the manufacturer of the derivative you are using...for example, Atmel apnotes have useful information and examples, even if you're using Philips or Analog Devices. (Of course you'll have to decide what applies or not!)
