Do you mean for if the braille device is connected to a serial port? If so, no. 
The serial ports are ttyS<n> (note the uppercase S), starting from ttyS0. 
Brltty will manage the serial port itself. Getty is for a text login.

Nothing. Just ensure either that udev is providing /dev/bus/usb or that 
/proc/bus/usb is mounted. Having both is fine, but only one is necessary.

Yes, that'd be fine, with one qualification. If something goes wrong early on 
then starting brltty as soon as possible gives a braille user the most 
independence. In other words, if a significant problem occurs before brltty has 
been started then he's stuck. It's like how early in the boot sequence should 
your monitor be started.
