I have a couple of suggestions for you.
Firstly, Software AG has an education service and they do offer a TN course which covers setup of TN, processing flat files, TN administration etc.
Secondly, Software AG also offer a global consulting service whereby an experienced consultant can work with onsite who can help you with your TN project.
Feel free to continue to ask questions in these forums, but considering that you are new to this subject then I think you would certainly benefit from one or both of those options.
