The brake fluid and coolant should be changed every two years (I think), but unless the A/c actually stinks or stops working, I wouldn't bother with servicing that, especially in a biggie like the 40k service.
Our resident mechanical guru Teutonic_Tamer and my independant garage both agreed on this.
All else ub7rm says is spot on
