To embed the artwork into each album, I believe you can do this in Get Info. Highlight the songs on the album, then click File-Get Info. A box will pop up and you can scroll through each song and change things like change or paste in artwork, change the artist's name (useful sometimes when artists names are spelled wrong, or more than one way), change album names, put albums together as part of compilations, change genre's, etc. I do this all the time. I especially hate it when songs are credited to Artist, Featuring Some Other Artist. I delete the second half so that they all appear together under the one Artist.
Hope that helps.
