well, when you drive your car for a while, you start feeling every little thing, and most importantly, how much pressure you should apply to the gas pedal, so that the speed doesn't switch to the next one (until redline of course). If you floor it while in Drive, and won't let go of the pedal, it should go up to the red line without switching to 2nd, then switch to 2nd, etc, so there's really no point in doing anything manually (1-2-3-D). Just leave it in Drive and pray that you have 6 cylinders (not sure if 95 comes with 6).

What they mean by power breaking is you hold the break while pressing the accelerator, and then let go of the break, pretty straightforward. Kinda similar to switching from Neutral to Drive while revving, but it doesn't **** up your tranny as much (but it does breaks :/). And seriously, please please learn how to drive first, oftentimes races can get into traffic and that's where u'll have to handle the car well.
Good luck.
