The 40% discounts have always been personal PIN-codes for as far as I know. The only general code that beat the 40% discount I've seen last year was the buy4get3free for bookings for early 2009 (which was prolonged later in 2009).
Talking about the 40% personal PIN code; the 40% is off of the rack room rate. You could use such a PIN for both a room only or a package, however it is only 40% off of the room rate. As allways (besides the AP-rates), you'ld have to have at least a one day MYW-ticket for all in your party to be able to add the dining. For a PIN-code that's no different.
By the way; I did get a 40% PIN-code for certain dates in 2009. Your traveldates were not included. The closest would be a timeframe ending on 10/30 and the next starting somewhere mid november.
PS: just had a quick look, can't find any general 40% discount at mousesavers either. (they keep a nice track of all of the discounts -pincodes excluded- offered by WDW over the years.
