Not really on the list of cheap and easy, but can save alot of trouble and money in the long run, I recommend installing fuel pressure guages on these 6.0's to monitor the fuel filters. My brother installed them on his '04 and my dad's '06 last winter after Ford denied warranty on four failed injectors on the '06 blaming it on plugged fuel filters. They have come in handy as dad and my brother are able to now tell that the filters are plugging well before the recommended 10,000 mile interval. Just a suggestion.
