I own a 1994 Camry it currently has 204,000 miles. Everything on your list I have done to my car also. I just did the filler neck. The part on Rockauto is under 60.00, mechanic charged me 50.00 to put it on. Ask around work or talk to friends for advice on a mechanic. I found mine this way and it has saved me thousands on repairs over the years. If the car does not have too much rust keep driving it. My car IMO is amazing for being 21 years old. Doesn't have any creaks or rattles, is really quiet, and averages about 26 mpg in mixed driving.
