Welcome!
It sounds like you have a great maintenance catch-up plan. Add a tire check to it if you haven't already had a look. Check tread
and date codes. Older tires are dangerous.
You're bound to see some hype over the IMSB...don't even read it. Check your oil filter at the oil changes, but that's it. You have a dual row IMSB, so no worries.
The best service manual is the Bentley. Pick one up. They are invaluable.
