How can I determine whether my piston is reusable so as to replace just the piston rings?

The most common problem of a piston that needs replacement is in case there are scratches on its body.

What other parts I may need to replace when replacing the piston rings?

To replace the piston rings you need to disassemble the engine, so you also need to replace the cylinder gasket.
