We will be in Naples for 4-5 nights in mid March. We were there before and did the main RS walking tour and sites. Does anyone have suggestions for other places we should definitely see? We like to see low key sites and don't mind taking public transportation to ger there. We will plan to visit Pompeii and Sorrento, before we head further south. Also, any favorite restaurants? Thank you.
See my reply to Chani (those sites are probably covered under the RS walking tour, but I am not sure)...

I enjoyed a daytrip to Capua, very nice arena and some other Roman ruins.
In Napoli, Carmine's restaurant on via dei Tribunali is old school Napolitano, surrounded by pastry shops.
Da Attilio for pizza.
I suggest San Lorenzo Maggiore (Conventual Friars Minor) Via dei Tribunali 316. Entry to the basilica is free but there is a leaflet guide to the basilica describing its 23 side chapels that you get with entry to the museum complex. You may be able to get this guide, for Euro 1.50, if you decide not to visit the museum. The museum entry includes access to the ancient Roman streets below ground but they are not that remarkable.
Nearby is San Gregorian Armeno containing the relics of St. Patrizia in a side chapel on the right near the main altar. Her story is similar to St. Gennaro (St. Januarius) with the liquefaction of the blood taking place each Tuesday at the first morning Mass, I think.
This church is open mornings only 9.00 to 12.00, a little later some days.
Churches are usually closed from 12.00 or 12.30 to 4.00 or 4.30 ( or 5.00 or 5.30).
Museums are open all day but may be closed one day or half-day per week. San Lorenzo museum is closed Sunday afternoons.
If you didn't see the Cappella Sansevero, be sure not to miss it and its amazing sculptures. While the Veiled Christ is more famous, I was even more blown away by Disillusion (how the sculptor got stone to look like rope still amazes me). And then there are the creepy "anatomical machines" in the basement.
And the Santa Chiara complex.
