If you don't already have any - I would definately do some hours in a single engine complex (preferably of the same manufacturer).
If you have complex hours - then just read the book (or watch the video - but note that the videos tend to be FAA orientated and not ALL the information agrees with CAA/JAA principles and ideals).
Enjoy the course - GREAT fun (even just taxiing the beast).
Fancy giving us a blow-by-blow account of the lessons and test?? Lets all learn from it!!
Good luck!!
