Hi, Tim. Despite your issues, please do not underestimate your professional abilities! You have impressive technical and training skills to fall back on when needed.

India is a very diverse nation and you should try to acquaint yourself with its culture before going, e.g., it will not be possible to shake hands with some Muslim women, you don't want to discuss the delish pulled pork sandwiches of North Carolina with Muslims or BBQ beef steaks with Hindus. Knowing the culture will give you more confidence dealing with your corporate people over there and will impress your managers.

Also, know what to wear. In some cultures, even if the weather is warm, shorts and t-shirts are not appropriate. (I learned this when I went to Chile.) Look at it as an opportunity to learn and grow professionally - and to meet the people who you have been dealing with - rather than as a test of your issues. I hope you have a great time!
