This paper you got should be equal a 学习驾照 by law. It seems you are eligible to take road test immediately (you must have driven 2 years or more in China).
Auto transmission is much simpler than manual one. However, you'd better to practise it in advance to cope with the test. You are going to be tested after all.
Actually the major challange is not how to operate the car, but the driving habits and courtesy. You may have to learn and practise that.
