the answer to your question will depend not so much on the vehicle, but on the
wheels you're using. one thing for certain is that you will use 12mm diameter
bolt. the length, the ball/conical will depend on your wheels.

If you are still running your stock*wheels just get them at your dealer. You'll pay a bit more but if there's anything wrong with them you can return them there to get the right ones. Alternatively you could pull one of your current ones and then measure it.
If you're swapping wheels* your other answers are spot-on.
I have a 2000 E320 and the tire shop lost one of the lug bolts when mounting new tires. My MB dealer no longer can get the lug bolt like my car was delivered with. The new part fits the wheel ok but is shorter so its head is recessed into the wheel like all newer cars. I finally found a junk yard that had the old (original) length and I bought all they had (three) because they didn't know the value of such a scarce part. I am keeping the two extra ones as valuable spares. By the way, the tire shop reimbursed me for the total $3 I spent on the three junked bolts.
