Yup you can't go wrong with malabar coast + goa...can add bombay, hyderabad and delhi/agra as well for sure.
All have lot of connections with arab culture and are well traversed by people from the gulf these days. But you are right that kerala (malabar) given the ancient spice trade etc...has an especially long historic connection to the Arab region....you should feel quite at home, they are hospitable folk too. There are many resources, and you have posted many already I remember, that give Arab tourist experience + tips for new visitors to Kerala etc...that are very helpful.
Cuisine, tourism and people to people relations can help enhance bonds of friendship and cordial coexistence.
Many people forget that Arabia and South Asia traded for at least 5 millennia. Since the time of Sumer, Magan, Dilmun which were contemporaries of the IVC, although Sumer and Dilmun are a bit older.
Similarly with Western and Southern India. For instance it was no coincidence that one of the first mosques built outside of the Arab world was built in South India. Later China followed (Guangzhou). Not a coincidence either.

It is a very interesting history, especially if you include the Indian Ocean trade.
I hope that differences can be overcome.
I also read that Arab countries were quick to offer help to Kerala during those unfortunate floods not long ago.
South Indians have a good reputation in KSA. Majority of people from India in the GCC are from Kerala and South India. I have noticed that South Indians on PDF seem to be more knowledgeable, less ignorant and know their history.
It also seems that South India is the best performing region of India overall. Most of the negative news that you hear from India, correct me if I am wrong, does that not originate from Northern India?
The South seems to be more tolerant. Less caste system (if any, not sure about that as well), fewer Hindu conservatives, no obsession about beef etc.
Anyway it is hard for me to judge when I am yet to visit India. All I know about India is what I have read, heard and from my interactions with Indians in the GCC and the West. If visits to Indian restaurants count in both places, then that should also be mentioned.
