If you are looking for extra work then how about:-

Remove the prechambers and clean them out - apparently they get gunked up over time. I will check this out

Refurbish your starter motor replaced last year :)

Refurbish your alternator yes thank you

Front crankshaft seal if there is any evidence what so ever that it has leaked (much easier to reach it now!) I will check this out thanks

Replace your oil cooler lines for the automatic transmission and engine if you have them.

Oh yeah I forgot to say... whilst you've got the coolant drained tackle the thermostat housing. You often get corrosion on this bit - the bolts get welded / corroded into place. This is also a 'much easier now' job.
I have all the parts off and cleaned up they are still in good shape. I also have a 1 year old 3 row recored rad to go with the engine.
Same goes for the vacuum pump (but you have already said you're looking into that).

And replace your engine mounts with new ones when you fit the engine! Yes

Should I replace the intake & exhaust gasket or leave it alone? I did not remove this yet.

I guess I would have recommended running a compression test before pulling it out of the car. If it is good I would do nothing more than superficial stuff as mentioned above. It is very hard to tell without documentation how many miles a benz has on it.

Change the Oil in the Fuel Injection Pump. If there is no plug to drain they Oil I have read you need to uses something with a tube (Turkey Baster with some skinny tubing attached?) to go in through the Oil Fill hole and suck out the Oil.

There should be some info on that as I read it here on the forum.

Good one Diesel911

That has reminded me about the intermediate shaft play...

When you remove the vacuum pump (as planned) check the end play of the intermediate shaft and see if it is loose.

This is the bit on these engines that shuttles back and forth (with wear) and then wrecks vacuum pumps.

You probably won't be able to make a really good measurement of this play (use a DTI) with the injector pump still on but if it is dangerously loose you should be able to detect it.

However, if you are going to remove the injector pump...
