Congratulations on pursuing your dream! The first step to learning painting and sculpting is to get a solid foundation in drawing. Here is a 'how-to' book that is perfect for beginners:
http://www.amazon.com/Lessons-Classical-Drawing-Essential-Techniques/dp/082300659X
I am a full-time student of the author- I even have some drawings in the book! "Lessons in Classical Drawing" is the closest thing to actually being in an atelier program. The book comes with a DVD tutorial to give a more complete learning experience.
I hope this is helpful. Best of luck with your studies!
