You can buy hard copies of the books, make sure you download the associated sound files.
The above books are about developing right hand dexterity.
Getting a teacher - you can do that, but because you are an experienced player you probably don't need one. A teacher can give you insights into technique and music interpretation though.
Also, I have the 120 right hand exercises in GuitarPro (notation and tab) and do it occasionally. I should do it more. I don't play classical style, but I recommend this.
