As far guides to the city, Expat guides to New Delhi & Mumbai would offer info about transportation, entertainment, etc. You may also want to look at expat blogs in India.

Anyone have recommendations?

India is nice place to visit or spend your vacation . India is full of divine destination if you are planning to visit india than must go for rajasthan trip awesome place i'll advice you to go with yourtripadvise for tour package .

 

4 days in Delhi, Agra are adequate. You can spend 2 days in Delhi, visit Agra in morning and come back by night. There isn't much to see in Agra except Taj Mahal. Agra fort is much like Delhi fort . You can try Fatehpur Sikri too. It's a nice place.
Due to some historical reasons (about which I can't go in detail), there are not many temples in this area. You can try Akshardham, Lotus, Bangla Sahib GUrudwara and Birla temple in Delhi. Rest are just mughal mausoleums.

As far as wildlife parks are concerned, I'd suggest Jim Corbett and Kanha. Latter is near world famous Khajuraho temples and the place has much to see and explore. I personally loved the place. If interested in ancient Indian history and temples, you can also try Orchha.

Not much knowledge about beaches, but I've heard that Andaman island beaches are the best
