Any particular advice on preparing in-ground mint, thyme, rosemary, tarragon and basil plants for the winter? These are some staple herbs we've used all summer. Pretty sure basil is an annual, but also pretty sure the others are perennials. Would like them to flourish in the spring.

Yes, your basil is annual. Enjoy now.
The others should be okay without any effort except be aware that rosemary is not terribly cold hardy. If we have another very cold winter, you may want to protect rosemary with a burlap windbreak.. If you mulch around your herbs, the mulch should not touch the stems, however it can moderate temperature fluctuations.
Mint can become an invasive nuisance if it's in a spot where it is happy. We recommend planting it in a container.
