I don't recall ever getting those two small orings included in with the filter. Usually just the large oring for the lid and the washer(s) for the drain plug. Is there a brand that comes with the two small rings I the kit?

Oh yeah... Definitely make sure the big oring stays in place as everything gets closed up. Oil everywhere... Benz there done that.
