How to program the Rapberry Pi to work with external buttons and devices?

In general, I need to implement the following project.
Linux system installed on Raspberry Pi. Connected to Raspberry:

  • 5 external remotes with Bluetooth buttons . They send signals from the outside in the form of 0, 1, 2, etc.
  • 10 time control buttons (start, stop, pause) and system (setting, modes, etc.)
  • Monitor 5 inches Raspberry. It displays system information
  • External monitor via HDMI. Displays information to the public.

I need to write software and build a system.
The questions are:
  1. How to automatically display graphics software on the external monitor when an external monitor is connected. You want the information to be automatically displayed to the public after an HDMI connection.
  2. How to disable unnecessary system components. I need the Raspberry to only process button presses and display the image on an external screen. It is necessary to achieve a high speed of operation without failures.

Yes, you do not need books, but to be able to use Yandex.
1) Or do you think - there are books called "How do I receive signals from external buttons. How to receive signals from buttons and define logic in Raspberry. "?
If you don’t know how to implement the protocol, look for implementations and remake them for yourself.
2) the question doesn't make sense. How to display data when connected to a computer monitor? - turn on the computer!
3) for the lazy, there are even online distribution builders with a choice of components.
For independent - the floor of the Internet is crammed with step-by-step instructions on how to build your distribution. See point 1.
