Welcome to the forum. You should have asked here before giving the go-ahead for the radiator and engine mount. The big problem with everything you need is that your being quoted dealer prices for parts and dealer labor, which is probably the highest you can find.

Any decent auto maintenance place (Firestone, Goodyear Tires Plus, Kimmel etc.) can do the work for a lot less. We can't see the actual damage or condition of the hoses, radiator or engine mount to see if your being taken for a ride on those parts, but dealers make a living on replacing parts not covered by warranty so anything they can talk you into is gravy on their plate.

90K isn't a bad time to replace the timing belt and water pump (I have 92k now and looking around for a good place) but I've been quoted $900 for more parts than what your getting (newer tensioner, all the belts plus plugs and wires).

By the way, even at $143 for replacing the wires is way too much and always replace the plugs when doing the wires since they are right there in the same area. That's if they didn't already replace the plugs, but you didn't mention that they did in fact you didn't mention what they did do to help the rough running engine the first time you took it in.
