Now that you have the camera itself and enough batteries and memory, I'd recommend buying and reading the "Photographer's Guide to the Sony DSC-RX100 V: Getting the Most from Sony's Pocketable Digital Camera" by Alexander White -- I just bought it two days ago and have been reading through it (the e-book edition is $7.99 on amazon) and even if you already feel as if you understand everything you need about the camera, it seems almost certain that you'll find some new tricks or unexplored menu options described in this book.
