I'll leave the pies and tugs up to others. As far as the spanking, though, I think it should be one spank for each mile per hour over he was driving over the limit on each ticket. (In other words, if he got caught doing 70 in a 55 zone each time, he'd get 15 swats for each ticket - or a total of 45 swats.)
A ruler is a pretty mild implement, so don't feel like you have to go easy on him.
I'd also suggest that he be bareassed (if not bareass naked) - and over your knee - for the spanking, which I'd administer before the pies and chain tugs.
