The 500/550/560 (including the 560 Ultra) are all the same type as far as everyone is concerned. You don't have to do an EFIS course for the 560 or Bravo - although it would be a good idea!
The Excel 560XL is a separate type, as is the 525 (original CJ). The CJ1 and CJ2 are different types.
Basically, before everyone got excited about ratings, Cessna tried to get a one-off rating to cover all types. The powers that be are making sure that every new aircraft is a different type. The only ones that get away with it are the older variants.
Depending on which type you need there are TRTO's available in the UK, and Flight Safety in Paris cover some types too.
Good luck
