Doing the B service is not hard. If you can do an oil change, that is a big part of it. If you do a search, you should be able to find all the items that are done in the B service. It is unlikely it will be covered in the warranty as it is maintenance.
As for the warranty, I bought one with the GL450. Afterwards, I felt it was a waste of money. When I bought the E350, I passed on the aftermarket warranty. This summer, the GL450 needed close to $4000 of repairs. The engine had to come out. Warranty covered it. Also had a damaged tire at some point, warranty covered that too.....you never know.
