Is there more to this ....like something to do with the dealer computer software, individual car program or something sneaky that the the car makers have done to complicate what used to be easy?

I believe you said you have a Camry and I assume it's a 4 cylinder. You don't have to use Toyota plugs, NGK plugs are what we use in Asian vehicles. The only other thing I would recommend is silicone lubricant on the spark plug wires or coil pack ends, which ever you have. This prevents them from sticking to the spark plugs. Also check the holes were the plugs are for oil before you take them out. If there is oil you will need to replace the valve cover gasket.
