Welcome to the forum Lee, you'll find the members on here are a friendly and helpful bunch :)
I'm surprised the part number isn't on the inside of the lid. To get the correct colour interior trim (this applies to any trim) have a look in your owners handbook as there will be your paint code and interior colour code.
In terms of clutch judder, this isn't normal and I would advise getting the garage to look at it.
Cheers
