One step at at a time. First, practice, practice, practice rev matching without braking. In 3rd gear around 3k rpm, put the clutch in, blip the throttle and downshift to second and quickly let the clutch out. You have to do it quickly, any hesitation and it wont work. If you over blipped, the car will lurch forward, if you under blipped, the car will lurch backwards. Do it over and over again until you get the sweet spot so when you let the clutch out the car doesn't lurch.

Once you have mastered rev matching, then add the braking. Put the ball of your foot on the brake and apply some pressure, clutch in, move your heal or side of your foot to the throttle and while still braking, blip the throttle, downshift to second, clutch out, brake off. It takes a lot of practice, so just go slowly.

Then if you really want a challenge, you can move up to heal and toe double clutch. But that's another lesson.
