I'm glad you're enthusiastic. Classes are just for technique and interpretation. Also other musical studies. Don't get me wrong, I would totally encourage them because i'm a music major, but if you just want to learn how to read you can just buy a book. But just in case you are even more serious about the guitar, i would recommend a good one on one teacher who can teach you technique and guitar music interpretation. Just make sure he/she is "musical" and is using proper classical guitar technique. As for reading, I can email you the music for Asturias if you'd like and maybe something like Lagrima by Tarrega. then you can look up a chart on the internet so you can know what the notes are

well, my attempt on asturias wasn't satisfactory for myself, i played a lot of mistakes, but on the other hand, it WAS the most difficult part of that song, and i think my arpeggio wasn't too bad at all, i just played the wrong notes in the end :d but ur right, i should take classes to learn how to read sheetmusic, because now i have to learn by listening :-)
