Question: is it enough to change only front pads for track use (pagid yellow), or do we need to change both, front and rear ?
You will get different answers on this one. If you want to preserve the f/r brake bias, you should do all 4 corners. Leaving the rears stock means you will have less friction and braking torque in the back (I can only assume RS19s have a higher coefficient of friction than stock pads overall--not to mention the rears will be prone to fade with the stock pads), and your brake bias will be shifted further up front. Having said that, some folks don't mind that. I personally do not think it is a good idea, and do all 4 corners.
