Hi Andy,
When confronted with an utter beginner, I always recommend the same book, which is now out of print, but can be had for a song (used) from amazon:
https://www.amazon.co.uk/Jewellery-T.../dp/1840921978.
The members who see this will be yawning, but it will give you photos of the main tools, describe their uses, describe the chief techniques used, and offer simple projects for beginners.
You can also learn a lot from U tube. Here is the best of the videos for rings:

Most of the tools you already have will serve you well here, so don't buy anything more than you need for the project in hand, Dennis.
