Answer 2

As far as I know, any cheats that give you health, armour and ammunition will block 'One Man Army' (surviving a six star wanted level for 5 minutes) and 'Cleaned The Mean Streets' (capturing all 20 criminals through the police computer). Car and vehicle cheats only affect your game progress. You cannot complete Grand Theft Auto IV if you have used cheats.

Answer 3

They disable "Cleaned the Mean Streets" achievement.

Answer 4

Yes, certain cheats will disable certain trophies from being unlocked. But don't worry I have used them all and even have the 'Let Sleeping Rockstars Lie' trophie and many more.
