So no one else jumped in. I did look at the pin mapping a bit, and nothing jumped out as wrong. In your configuration.h, the mechanical DEFAULT SETTINGS starting at row 493 are likely going to require tailoring for your printer's number of gear teeth, Z axis screw threads, etc. The speed and acceleration values all seem high. Starting at row 330, the ENDSTOP INVERTING values are set to true; this could be right or wrong depending on how your endstop switches are wired.

Can you elaborate on the beep? Is it present all the time? Or it starts only when you try to do something and if so, doing what? Does it repeat? If so, how often? There should be small hole in the front of the buzzer - cover the hole with a piece of tape to dampen it while you're trying to figure it out.

Did your LCD supplier instruct you to use the G3D_PANEL LCD type in configuration.h? If not, try using REPRAP_DISCOUNT_SMART_CONTROLLER instead. That'll invoke a different pin assignment for the beeper - one of the things you're having issues with.
