First tip - revisit the ATP requirements of part 61 and make sure that you have the necessary hours and training -- obvious thing to say but it is a useful checklist.
ATP-CTP - not sure that you do in fact need TSA.
ATP training and flight test on MEP - no TSA required. ( since you already have a stand alone CPL/IR/MEP). Also no endorsement required for checkride as you hold equivalent foreign licence.
Getting the type rating added to your FAA certificate - sorry, can't help you on that.
