For the LCD, make sure you installed the u8glib library. The comments at the beginning of the LCD section says where to find it.
The sd card socket is enabled when you uncomment #define SDSUPPORT
For the full graphic smart controller, uncomment #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
Two ways to fry the drivers: install them backwards or connect/disconnect the motors when they're on. 8825 are installed with the pot on the opposite side than the 4988.
MOTHERBOARD BOARD_RAMPS_14_EFB defines a RAMPS 1.4 with an Extruder (hotend), Fan and a Bed heater.
