To get 150 Health, all you need to do is complete 12 Paramedic Missions when on a Paramedic vehicle. Once you complete the 12th mission, you will automatically get 150 Health.

To do the Instant Replay, Press F1. The Instant Replay will take about 15 seconds. You can do this everytime.

OK, as shown in the title, thisis a glitch not a cheat, but to make this happen, you might want to use some cheats. This is what happens and how you do it, go to the '8-Track' competition. Then once you get there, start and wait for everyone else to leave so they don't get in your way. Then after that, try and go over the fence into the audience ground. Once you go there you'll start sinking into a black like dimension!! Your vehicle will start falling and if you exit it then you will start falling(wtf!!)and he will say one of his falling phrases. After while, you will fall really hard and die =P.

P.S. I don't know if you have a parachute, what will happen but...GOOD LUCK!!

Thank You for Reading.
