Optical Endstops & Autoleveling - GT2560 Prusa I3

I am currently building my first own Prusa I3. I have chosen the GT2560 board because my boss had a 3D printer at work which I had to maintain from time to time so I am a little bit more familiar with this board.
After some issues with getting my stepper motors to move I now have come to the part where I would need to change the firmware to work with optical endstops for the X&Y axis [www.reprapsource.com] and a LJ12A3-4-Z PNP NO 4 mm proximity sensor for the Z axis to auto level. Also: has anybody else noticed that you have to turn knob of the LCD2004(+SD) in the wrong way (clockwise) to go down in the menu?
The opto endstops seem to work as the led reacts when the sensor is triggered but it seems that the auto level sensor doesn't response to any metallic surface beneath it with its led; I would need to look into it.
What would I need to change in the configuration file to make the firmware able to work with opto endstops and a proximity sensor?

In Marlin's Configuration_adv.h file you can control the direction for the Encoder Wheel for both menu items and numbers while editing them. Just configure them to your preference.

Thanks for the reply! Unfortunately I can't find the line where it would be defined/configured, could you point me towards it?

Update: I got the Y-Axis endstop to work but the X-axis endstop won't work with the same settings; now it always is on.

#define ENDSTOPPULLUPS // Comment this out (using // at the start of the line) to disable the endstop pullup resistors

#ifndef ENDSTOPPULLUPS

#define INVERT_E1_DIR false    // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E2_DIR false   // for direct drive extruder v9 set to true, for geared extruder set to false

They are called:

//#define REVERSE_ENCODER_DIRECTION
#define REVERSE_MENU_DIRECTION


There are two settings. One for the Encoder in general. And one for menu options.
