Help with Madurai trip with parents

I am planning to spend a day in Madurai with my older parents. The primary goal is to visit temples. We land at 4:30 pm, plan to spend the next stay in Madurai, and then drive to Rameshwaram the following day after breakfast. How should we plan our stay in Madurai to see most temples, and which ones? Any advice on shopping or things to eat would be great too.
