It's tempting to think that this is exactly the sort of thing that should be in WOTC's published adventures in the first place, but realistically, those adventures are so expansive that the number of things that could be added are endless. We get it into our heads that if we buy a published adventure, that's everything we need to run the game, but we will always need to work on integrating them into our games. They're a toolkit rather than the final product. Also, there are a million and one different layout possibilities, and every DM is going to have their own preferences.
Power Score RPG's guide is an excellent breakdown of the adventure, and is invaluable in giving pointers to organising your games, without being proscriptive or limiting. In addition, the whole thing is written with good humour, and a wide ranging knowledge of previous published incarnations of Ravenloft. Seriously, I couldn't even count the number of ideas from this Guide that I used in my Curse of Strahd campaign. This gets the absolute highest recommendation from me.
