i know how you feel bud. it took me a while but my list of things to fix is almost finished, it just takes time. you gotta expect this sorta thing from an old car. every similar age holden and ford i've seen has ALOT more problems than i've seen in mine and my friends' jap cars. these problems you have arn't huge and don't cost too much to fix. get the bigger ones out of the way like the radiator before it causes grief, and leave the cosmetic and comfortability for after.
my car has done ~150,000km. it missfires, idles a bit funny, it's running rich, and it needs a nice tap of the accelerator when cranking it over to get her breathing. apart from those few little things it runs like a dream. this is because i always look after the little things and change things asap rather than leaving it till a later date.
hope that helps
