I think I'm going to just have Toyota do the works and toss in a clean/reseat of the rear brakes, 305 for everything and then I have the security. I'd be more akin to DIY if my girls weren't involved - but since they are, that is where my concern lies...

Front brakes on most vehicles will wear faster than the rears since the fronts do the majority of the braking. The weight on the front end and the weight transfer under braking are the major reason for that. Your mileage, 42K, is not unusual for brakes to wear out depending on the driving conditions. All city driving in stop and go conditions will use them up quickly. If you truly are at metal-on-metal, expect to replace the rotor(s). That may not be included in the cost they are quoting you. With minimal wear limits on the rotors, it will be quickly ruined when the pads wear to the metal backing.
As for not turning the rotors, that is OK but far from ideal. There is a lot more to it than just the surface finish and trueness. It would be impossible to get a highly accurate measure of the rotors trueness anyway. Even minor variances will reduce the life of the new pads as they must wear in to match the rotor. During that wear in period, braking will be reduced due to incomplete pad to rotor contact, The rotors will also be impregnated with the old lining material. The new pads need to have a clean fresh surface to embed their own material into to create the greatest braking efficiency. A polished rotor may not ever let the pads properly seat reducing braking and creating squealing.
You are wise to consider your families saftey in having the brakes done properly. Brakes are no place to go cheap.
