Any parts that need special tools? I though there was something special about adjusting the oil pump chain. I previously tightened the oil pump chain when I dropped the lower pan and the chain was pretty loose so glad I did that. But should probably replace the chain as well, but not sure how hard that would be.

Although it's not a known issue in first gen S63 but certainly not a bad idea to do as preventative maintenance. I have been collecting parts for a bottom end engine refresh i.e. upper oil pan gasket, lower oil pan gasket, oil pump chain, rod bearings, rear main seal, rear coolant cover, motor mounts, and anything else I see along the way.
I doubt any specials tools are required but I'll double check in ISTA+ for you. You do need to replace connecting rod bolts, factory/OEM bolts have a 3 step torque process from what I remember. So I had planned go replace them with ARP or something (I haven't looked into it much just yet lol) but it's not rocket science - follow ISTA+ and you'd be good.
These things may not be in the worse of the condition but it's helps tremendously towards longevity of the engine.
