John- Welcome to Ferrari Life. The first big upgrade was at AN 51797 for straight center pipes and the really big one was at 52556 for the steering position sensor and 50 amp F1 pump relay. All documented in the 575 Technical Thread. More changes in 05 shown in the changes document in the same thread.
Good options to have are 19" modulars, Daytonas and leather shelf, and FHP, none of which mine has except FHP.
Ferrari dealers and big independents are usually the most reliable.
Prices are in the range you list.
After you read the technical thread, see what questions you have.
Present: 575M 135171
Past: Dino 246 GT 02984, 365 GTB/4 14009, 308 GTS 25125
Every day I look around, and if nobody is shooting at me, it is a pretty good day.
