ICantAffordIt, I'm not an expert but
1.- "PRL" is like a list of antenas of your carrier, so as you can imagine Sprint has his own PRL. Why sprint have more than one PRL? I believe they have diferent regions of "list of antenas" (depends where do you live) and Also I guess they have diferent "PRL" for "pre-paid" and "Plan" Phones. Which is the best "PRL" for you?? have no clue 'cause I don't have Sprint as my carrier. Why update/change PRL is important? because they add or rest "Antenas" in there Matrix Network. For example, in the stock rom (carrier original) you can update your PRL by OTA, unfortunately in most of the non-stock rom you can't update by OTA (over the air) you need to update it manually.
2.- "DCD carrier cab" is a list of setting/register for your device to make it work fine with your carrier. Again Sprint has his own DCD (sometimes they update it, but not often). If you don't apply the DCD cab you will have to change manually the registry for all the services (like voice, data, etc, etc) works in your mobile.
