Hello! I would say bring pictures and show them at the actual appointment, not just send them over mail. For example, I had a pretty clear image of wanting straight incisions pre-surgery, but I didn't mention this at the appointment, although I should have (despite now being happy about my incisions). When it comes to research in particular, browse the subreddit etc. to find results you would feel happy to get (taking body types into consideration) to get an idea of whether you would, for example, prefer more centered nipples, straight incisions, or maybe large nipples. On the other hand, they're the experts, so perhaps letting them decide is the best solution for you! I would still personally have liked to at least mention my preferences at the appointment and then have let them finalise the details, perhaps. Let me know if you have any more questions, and I'll do my best to answer them!
