The 95 E300D i just bought with 80k miles has a rather soft suspension (rolls on corners and floats on the highway, but no knocks or clunks). I had it on a lift and didn't notice any wear or degradation to the LCA or rear subframe bushings. I plan to replace the swaybars, shocks and springs with Sportline series parts. I've found the part numbers on a couple posts (here, here and here) and in the W124 Bible, however there are some discrepancies with the sway bars and bushings. (since solved)

Front swaybar : 124 323 68 65 (E300, Bible), 124 323 70 65 (E420), and 124 323 77 65 (Limo)
FT swb bush : 124 323 45 85 (E300, Bible), 124 323 50 85 (E420), and 124 323 46 85 (Limo)
FT swb bush : 124 323 51 85 (E300, Bible), 124 323 56 85 (E420), and 124 323 51 85 (Limo)
Rear swaybar : 124 326 19 65 (E300, Bible), 124 326 24 65 (E420), and 124 326 25 65 (E500)
Rr swb bush : 124 326 01 81 (E300, Bible), 124 326 01 81 (E420), and 210 326 08 81 (E500)

Which are the regular E300D Sportline bars and bushings. I'm not interested in the 500E or limo bars. Should I bother with the subframe and LCA bushings if they still look good? Hope you guys can help.

First, the '95 E300D didn't have the Sportline option package available in the US, only the E320 had it avaliable as an option. Your dealer or the free online MB EPC may be better able to zero in the parts.

ok, i figured out the correct numbers (edited first post). The question still remains, should i bother with the LCA and subframe bushings if they still look good? will it matter that much?

Will the LCA ball joints and subframe bushings make a performance difference? Unless they're in need of service, in normal driving, you won't notice a thing.

IIRC, all the new W124 LCAs (OEM) have the sportline bushings installed.

Since you're replacing the rear swaybar, it would be a good time to redo the subframe bushings.
