  1. For this you can use the file /etc/rc.local. Insert your command to this file before exit 0 and anytime you start your system the command is executed. Please ensure that he file is also executable.

  2. From your question, it appears you want to set screen brightness on startup. With current architecture (Xorg, not Mir or Wayland) you can do it like written on: How do I set default display brightness?
