The Writing Workshop... where to begin?

We recently read Nancie Atwell's In the MIddle: Writing, Reading, and Learning with Adolescents in our methods course. The writing workshop, as described by Atwell, produces affective writers and improves students' writing abilities. She works one-on-one with each student, holding conferences to ensure each step of the writing process is taking place. Looking back on my middle school and high school years, I cannot remember a teacher who went through each step of the writing process and held conferences with each student. This may take much time, but when used wisely, much can be accomplished using this writing workshop model.
Atwell's model is extremely affective in her classroom, but I am nervous of where to begin this process in my future classroom. The closer I get to student teaching, the more anxious I get about classroom organization, an essential element in the writing workshop and for a positive classroom environment. I plan on keeping the class as organized as possible to create a positive learning place. This will take time and effort, but I am sure I can effectively organize the class so that students can become better readers and writers.
