Hi Eric,
Welcome to EYB! I hope you'll find it as useful as I have.
Many of us are home cooks only, so I'm intrigued to know what you've found the most valuable from your restaurant experience.
Can't offer guidance on half those cuisines you mention, but I have some experience with a couple of them.
Indian: Julie Sahni and Madhur Jaffrey brought Indian cooking to English-speaking audiences in the 1970s-80s. Classic Indian Cooking and An Invitation to Indian Cooking are fine starting points -- with the caveat that India comprises many different ethnic groups, climates, and food cultures, so that no one book is going to cover everything thoroughly. But they both cover fundamental techniques and approaches to building Indian meals. Pick one or both and get the basics down before branching out.
German: Lüchow's German Cookbook (Indexing Now, soon to be released) covers authentically German dishes as served by the NY restaurant in the 1940s-1950s-1960s. Mimi Sheraton's The German Cookbook is a bit more faithful to German home cooking. The cuisine has been deeply unfashionable in most parts of the U.S. for a long time, but the recent surge in craft beer, sausage-making, lacto-fermented vegetables, and real slow-rise bread have set the stage for a revival IMO.
Chinese - will cover in another post in a bit.
