Answer 1

Take care of Perl, write a script using MP3::Info.

Answer 2

Two batch files:
1st) receives the name of an MP3 file as a parameter,
requests its bitrate (for example, via ExifTool),
cuts the bitrate from the output
if there is no subdirectory with a name equal to the bitrate - creates it
moves the file to a subdirectory with this named
2nd) runs the command file "1" from all files in the directory via for each
