Yes, rust is the biggest issue.

To add more to the list:

transmission (life-time fluid)
Low ball joints
Head gasket (96 and 97 models)
Wiring harness (96 models)

My 1997 E320 has no rust because I rinse it very frequently and try not to drive when roads are salted. However, the spring perches were still replaced.

Not everything on your list will happen to a particular model year. Looking through the history of my 1997, for example, the following were problems

transmission (valve body)
MAF
Low ball joints
Spring Perches
Oil leak
cracked dashboards.
creaking driver seat
