comparing the driver side versus the passenger side sway bar ends, the passenger side has more "fat" beyond the connection point. the driver side has no "fat" and is flush with the "clamp".

what do you recommend?

Your best course of action would probably loosen up the connections at the LCA and the brackets that extend down from the frame's box channel and try to shift it back into a more centered position.

That will likely have little effect on the issue with the wheels, unless you can find some obvious damage that would point to the "how and why" the wheels are positioned as they are your best bet might be to get things as straight as you can by eye and take it to an alignment shop where they can lock it in place and establish some reference points to measure things from.

If you explain to them what you're after they might be willing to help you figure out if something is within the range that can be compensated for or something is too far out of position. Usually you've got to pay first but if they can't get it done you'll get some percentage credit if you bring it back afterwards.

If you have a lift or the ability to get the vehicle up off the ground where you can get on a creeper and skate around underneath freely and some time you could possibly measure things yourself, you'd need a distance bar or some reasonable facsimile, but the Mercedes literature for Group Index - 40Wheels, Chassis Measurements has all the specs and the measuring points for the chassis. This info I know is available in the TDM-Technical Data Manual and it might be in the Body and Chassis FSM also.
