Quite a list of parts there...
For the engine mounts id suggest sending them to adam "SSS" to get them solid filled. They'll last a lifetime and you wont have to do them again.
CV boots,swaybar bushes, control arm bushes, steering rack boots, gear selector bushes, drive belts, battery clamp, oil filter, fuel filter are all things that are a routine maintenance thing. Your better off spending the money on brand new stuff if you plan to keep the car, as replacing it with second hand stuff, will only need to be replaced again shortly.
If you dont have a supercheap auto or repco in NT and need to get it shipped up thats another story but if you can buy brand new, at least then you'll know that you wont have to worry about it again for a long time.
