Highly recommend the Gill Rapley Baby-led Weaning Book. Also, the River Cottage Baby and Toddler Cookbook is excellent. We used to cook things from there even before our daughter was born, and we still use it regularly now (she's 2). If you do baby-led weaning, you don't need any equipment other than maybe a high chair (and you don't absolutely *need* that right away) and some bibs plus something to wipe hands and faces. We use just regular flannels for clean-ups. We didn't use any bowls or cutlery at first. Everything just went on the tray and she ate it from there. Maybe started to use a bowl around 9 months and spoon and fork sometime after that, so no need to run out and buy it now.
I've also found the recipes here to be really great and we made a lot of these when our daughter was a baby: https://littlegrazers.com/
