For $25-30 bucks you can get old copies of the Factory service DVD on ebay, you just need to set the date back on your computer to use it. If you look around you can usually find these for free on bitorrent sites.
For $16.95 a month you can get a subscription to the factory service manual, TSB's and other vehicle specific information from motorcraftservice.com.
This forum is definately the best source for free information, if you have a problem search here and it's probably been covered.
