Visiting the Ancestral Homeland

My wife and I are visiting Sicily from August 25 to August 31.
We land in Palermo at 7:00 am on August 25. Pickup our rental car and drive to our hotel in Mondello.

The 25th will be a relaxation day pool / beach and dinner in Mondello. Any recommendations for restaurants?. We prefer to the extent possible neighborhood type restaurants serving typical food.

On the 26 we are driving early to the Valley of temples in Argrigento to see the ruins. We would like to stop at a winery on the trip back to Mondello. Any suggestions for wineries between Argrigento and Mondello? Any other suggestions are appreciated.

The 27 is our Palermo day. We are interested in street food and visiting the catacombs. We are contemplating hiring a guide for 4/5 hours and then dining in Palermo. Any suggestions for sights to see and places to dine are appreciated.
