I kinda get when it's time to replace the cassette, but there not much out there on about when to change chain rings.

If the drivetrain starts skipping it is usually time to replace the chain and cassette. What you can do is try a new chain first and see how it goes, but I normally replace chains/cassettes together. If you still get some skipping it can only mean the chainrings are worn.

I like to do the measure test for chains as well as an indicator. Measure pin to pin over 12 inches. If it gets more than that replace the chain. This way you might get by with keeping the cassette, but it will definitely prolong the chainrings which can last for quite awhile.
