I am a Cad Manager for a large consultant, and was hired strictly for the implementation of Civil 3D and to train 100+ employees. There will be hurdles in front of you. The most important item to have setup is your template! Civil 3D's whole world revolves around styles! We are almost a year into our transition from Land Desktop to Civil 3D and my users are now becoming comfortable and confident with the application and we are starting to see gains in productivity. It's imperative that you seek training, this is almost impossible to tackle without a good instructor.
Just my 2 cents.
