You're asking a lot of questions in one question. Perhaps asking new, separate questions will get more responses. A couple of Google searches turned up these links for issues regarding "best practices":

• https://github.com/ethz-asl/ros_best_practices/wiki
• ROS Best Practices
• When should I split my code into multiple packages, and what's a good way to split it?
• Roslaunch tips for large projects
• Best practices for organizing a project [closed]

The question "how do I write my own controllers?" is very general and difficult to answer. Try to narrow it down a bit and ask a new question.

Edit 2:

Are you sure that you've updated your code and re-compiled it? Your repo still shows the same code missing the closing " `"` on line 6, as I pointed out. The message /home/rmb/gopigo_ws/src/pd_controller/src/pd_controller.cpp: 
`/home/rmb/gopigo_ws/src/pd_controller/src/pd_controller.cpp: line 9: //std_msgs: No such file or directory directory` means that it's looking for a directory //std_msgs which would make `//std_msgs`

Edit 3:

You're mixing up data types. Your publisher has the surp::Int32Stamped data type, your calback function encoderCallback is expecting a data type of surp::Int32Stamped in its argument while your subscriber is expecting saying that the data type will be surp::Int32. .

The error in your comment gives this away. The error in your question is unrelated. You should update your question with the full terminal output. That's the best way to get help from everyone.
