I just received my first RioCar and ofcourse I can't leave it alone... I have to mod it with illuminated buttons...

I plan to use red leds, therefore I have a couple of questions. Since the white leds normally have Vf of about 3.5V and with 1kOhm resistor that should equal If of about 1.5mA. I guess I should be quite safe using a 2k2 resistorpack and low-current leds and not blow up the PIC? I could probably use 1kOhm as well since most PICs can sink 25mA...
The transistor for the knob is a PNP, isn't it?

And yes, I am able to solder the resistorpack...
