Extension of truck driver’s license. Modules when to register?

Hello I have just completed the 5 modules. So the EU professional driver course, which you need for commercial journeys. My driving license C/CE, acquired in 2003, expires now in July 2013, and has to be extended for another 5 years. My question. Should I have the driver’s license extended now and have the modules registered? or can I wait until July 2013 and then have the modules entered there? What is smarter? Would both go? Additional question. If I had acquired this licence before 2000, did I have to go there only from 50 years? I am now at the end of 30. Can you please write something to me. Greetings G2S
