ickle black box - G-WHISKY is slightly wrong with regards to his post. As highlighted in your post, you must have finished your training, successfully completed the test, and applied for the rating before the 30th June 2002.
And to clarify your situation, you will not get any dispensation off the approved IR course for holding an IMC rating if you are adding it to a JAR-FCL PPL - you will have to do the full 55 hour course (assuming you are doing a Multi IR). If you are adding it to a JAR-FCL CPL, you will benefit from the 5 hours reduction making it a 50 hour course.
