What are lessons like?

I'm signing up for violin lessons next week and I was wondering what the first few lessons are like. I'd like to think that I am better off than the average beginner as I can read music. I've played piano, flute and guitar. I also know music theory as I took music theory courses, and I know most of the fingering in first position. I also bought some books, like Violin Scales and Arpeggios in One, Two and Three Octaves based on Carl Flesch. I figure that learning the one octave scales and arpeggios will help me for now, until I learn more than just first position. I probably have ten different books, aimed for beginners I've also learned some stuff on my own. The Twinkle Twinkle variations from my Suzuki book, some of the violin part in Beethoven's 7th symphony (allegretto movement), Ode to Joy, etc. I'm working on Bach's Bourre BVW 996 currently.

I don't want to learn anything else for the time being. I'm afraid of picking up bad habits and then having to relearn everything. I'm really excited to start lessons though!
