Do a Google on the Delcamp site for a thread entitled Let's learn Sor OP 60 together. You may want to get Sor's Complete Studies book. I bought the Tecla 101 edition several months ago, off of e - b a y for 20 dollars, as it was used.
I think being able to play Maria Luisa and Carcassi's Sonatine OP 1 is a great start. If you are able to execute these pieces well, I wouldn't call you a beginner, no sir. My wife is what I would call a total beginner, as she is still learning chord shapes. I wouldn't worry too much about what level you are at, as there is always going to someone who plays better, or at a higher level, than you or I, or anyone for that matter.
I have only been playing classical guitar for almost 2 years, but I have played other kinds of guitars since 1984. The highest level piece that I can play is Bach's Bouree in E minor, and that is supposed to be a grade 5 piece. This is what I've been able to do on my own, without a teacher. But, supposing I could go back in time, to when I was your age, I would definitely find a good teacher. If you have questions regarding certain pieces, you could check the Delcamp lessons to see if there are any of them under certain levels in the forum's lessons.
You might want to get a book of Aguado studies too. Also, 39 progressive solos for guitar, by Ben Bolt, is a good book full of studies and pieces that starts with the easiest pieces at the front of the book, and progresses with the more difficult pieces at the end of the book. It comes with a CD, so you can hear how what you are hearing, corresponds with what's in the notation and tab.
Well, good luck in your endeavors, and see you around the Forum.
