After some research it appears I have everything for a '21 kit including 2 small plugs which are probably the blank power jets the seller didn't think he had. I've never had an NSR carb apart yet, so I'm not sure if that's what they are or not. Doesn't matter yet because I have 130-155 jets so I'll need the power jets unless I buy the bigger mains.

This is fun and will be until I have to start tearing down and adjusting over and over and over.
