*228 Option 1 is used when you change the phone on a number and need to program that number into the phone. It loads the phone number into the phone, loads the roaming list and resets couple of other things to the default (lock code changes to the last 4 of the phone number). Usually you only do this once on the phone. If a tech tells you to then do it, but you don't need to do this according to any regular schedule.

*228 Option 2 loads the tower or roaming list into the phone. This is tower list for the entire country not just the local area. If you're going to travel do it in a verizon area before you leave and you will have the latest tower list for where you're going.
