Looks to me like that piston has a LOT of hours on it. Typically, the intake side wears faster than the exhaust side, and the exhaust side of yours has worn off all the machine lines. I would not replace just the ring. Get a new piston.
Your rim only shows minimal wear and has a lot of life left in it.
I can't tell about your bar. Most likely it needs the rails dressed and will be good to go.
