I need to find the parts to make this work off of one board. I need 6 PWM pins for lights. I need a keypad or atleast a 4 button layout and a display of some sorts. 2x16 lcd? Any ideas on some hardware thats light on the pin use? What would you use or suggest?

6 PWM channels, input device and display

Well that's two more so you still have two pins free before you need to consider any port expanders.
