i want to develop an eye for when a cassette will need replacing. Any pics of cassettes with different degrees of wear I can take a look at? like a photo record of a cassette new, at 1000 miles, 5k miles, worn out etc?

I can't tell just by looking unless they are really, really bad.

Chains are cheap. When the distance between 24 links of chain exceeds 12 1/16", it's time to replace the chain. If the distance exceeds 12 1/8", you'll probably have to replace the cassette too because the new chain is going to skip in your favorite cogs.
