I was just reading the June issue of OXM and they actually had a great write up on GTA4. One of the things they said was that you should save the game frequently so that you have a save point before making any of the moral decisions in the game. They said that these decisions can affect the final outcome of the game and if you make the wrong choice it can affect the 100% completion. I save after every couple missions and if there have been no moral decisions since the last save, I just overwrite it.
