Answer 1

iTunes doesn't use file names to determine how music appears in your library,  Rather, it uses metadata that is split between:
data elements that are embedded within the media files
data elements that are included in the entries in the iTunes database
No amount of reorganization, renaming or other manipulation at the file level will make any difference to how songs will appear in iTunes.  Using your example:
the value of the track number element is 1
the value of the artist element is "Elvis Presley"
the value of the song name element is "Blue Suede Shoes"
Depending on how you configure iTunes then the file name is either:
completely independent of iTunes (i.,e., the file containing this song could be xyz.mp3)
dependent on the metadata managed by iTunes, (i.e., when you have these two options set:
then iTunes will set the file name to be 1-01 Blue Suede Shoes.mp3 where:
the file is in a folder called "Elvis Presley" (the name of the album)
that folder is in one called "Elvis Presley" (the name of the artist) which is in iTunes Media\Music
Going back to your question "How to make iTunes read the song's name/singer from the file's name" the answer is simple - you can't, as this is not how iTunes works.  There are some third-party utilities that you can use to set some metadata element values based on parsing of file names which might be a useful first step.  However, to use iTunes effectively you should really forget about / ignore file names - manage your media using appropriate metadata and allow iTunes to look after file names behind the scenes.
