Joystick maximum is 254. Your code does something with the joystick value to get a number from 0 to 127. Your
lookup array only goes to 126, so you're falling off the edge and picking up an undefined result. Make your table bigger by one. You might also consider initializing it as part of its declaration rather than having a whole bunch of code in a function to do it.
Code:
static char lookup[128] = (0,0,0,0,0,0,1,1,2,2,2,3,4,4...);

3)There is rhythmic pulsing coming from the pwms (i hooked up a servo and it kept moving without any joystick interaction)

You're using pwms 13-16. They are generated by the RC user processor. When other interrupts are being used in the system, the pwm outputs jitter. Change to other pwm outputs, which are generated by the master processor and are not subject to the same interference.
