Do you actually need to replace the door handles or are they just a bit scratched from years of use? If the latter, then its much cheaper to get handle covers which slip over the originals. Whoever owned mine before me clearly wore alot of rings as the door handles were scratched to hell (and steering wheel plastics a bit too) - I got some chrome covers for £55. Made a massive difference. You can also get them in colours to match your car, piano black etc
No idea about mudflaps I'm afraid.
