Girona is wonderful and, being fairly large, will not be dead in November. You couldn't see it all even if you spent a full day there. The art museum is not large but is excellent. There are scattered small craft shops in the historic district. Probably clothes, too, but that's something I usually ignore in Europe. Spain's known for leather goods, so watch for shoes, purses, wallets, etc.
Figures I didn't really visit, just changed buses there on my way to Cadaqués.
In Cadaqués there are at least two large ceramic shops with production goods (generally not one-of-a-kind pieces). One was on the main street running from the waterfront up toward the bus station; the other was on the waterfront to the left of that main street as you face the water, sort of hidden along a row of restaurants. Some overlap of stock; I thought they might be owned by the same person. I liked the colorful and quite inexpensive pottery, but it was heavy. I also saw quite a few art galleries (paintings and the like), but they mostly weren't open the day I was there, which was a Tuesday in late August. I don't know whether it was the time of day or that it was mid-week. I think some of the galleries are by appointment only.
I fear that Cadaqués will be rather dead in November. It was pretty in July, all white-washed buildings with dripping bougainvillea. Maybe you should check with the tourist office in Girona about the sea urchin trips and the likely general situation in Cadaqués before starting on that excursion--assuming you're not also interested in the Dali sites--since there's so much to see in Girona itself.
