I understand your hesitancy with free downloads. However, there are many well-established tag editors that are safe to download, based on significant user experience.
MP3Tag is one of them; The Godfather another.
As to tutorials, there are many out there; you could try a search engine search. Here are a few, on ripping music and on tagging files–they’re not perfect, but a start. Actually using the programs and their included help files–_which I greatly recommend you read, as the product manuals–_will help.
