@Nikkil > Regarding the music naming, as others have stated, it sounds to me like the ID3 tags of the files were not properly stored. You can change those within rekordbox and it will update the file itself so if you were to load it elsewhere (like iTunes), it would be correct.
You can use 3rd party tag editors / managers to clean up that data.
The jog wheel rotation settings are up to your preference, there is no "best" setting. Same with the fader curve speed.
