You will find hundreds of thousands of threads here on oils. For me it boils down to two parameters:
- 20W50, which is factory specs; will turn out to be mineral, not synthetic
- ZDDP content around 1600, which in Europe means Valvoline VR1; in the US many more options, I guess
As for the oil change - I do it at home, just ask a real mechanic to help me get rid of the old oil.
Since you have a good write up on oil change, you can probably take it and go to some good service and take them through the procedure. You would have to bring your oil and your filter most likely. The peculiar thing is the thick seal check and replacement.
I did it several times on other items: scheduled a visit at Mercedes dealer and worked with the mechanic with BBB in my hand and all the materials in my boxes (e.g. yellow plated screws) on whatever we needed to do. Of course any spare parts used that I could buy from them, I bought form them.
I am not a mechanic, but from what I can tell the particularities in our cars (different than modern standards) are:
- replacement of the seal ring on the filter housing bolt
- oring replacement in the filter housing
- checking the thick seal between the filter element housing and the filter base
I think that is all that is different.
