2005 W163 ML500 service, preventative maintenance recommendations?

[satyr]

Hey all,
We just drove our new to us 2005 ML500 (got home only 6 hours ago!) and wanted to hurry up and post here to see what service recommendations you guys have for us. It's got 113K on the clock and no check engine lights. I plan to get the tranny fluid and filter done soon, and to replace the tranny electrical connector with the o-rings that often leak. I will also get an oil leak that appears to be from the colling lines that run to the radiator addressed. Ball joints were recently replaced. Is there anything else that we should take care of at this point to prevent future problems? Are there any other general services that we should do?

Thank you as always, for any recommendations you have for us. -J
