There is a better exploded view on the net somewhere, but I can't remember where. The barrel is held in by a couple of press fit pins. Drive those out and you an probably use a brass or aluminum drift to drive the barrel out forward. There is really no reason to remove the barrel for normal maintenance or even refinishing.
The working parts are all retained by an assortment of pins and screws. It is easy to see what is what. I usually remove them all and shake the receiver and all the parts fall out. Watch out for the trigger spring and plunger. The bolt is easily disassembled by driving out the pin thru the bolt sleeve. The extractors usually don't need removal but they can be removed by driving out their pins. Don't lose the extractor spring.
You can polish the sear shoulder that catches the firing pin notch, but don't alter the angle or you will probably need a new sear.

The left extractor is beveled to allow the case rim to be pushed forward by the ejector and then pivot on the right extractor hook and out of the action port to the right. The ejector is a fixed vertical blade that runs in a groove in the bolt bottom. Dual extractors are common on bolt, pump and lever action 22's.
