Most of the plants you listed won't do very well in shade.
Fuchsia hybrids will do well, but not CA fuchsia (Epilobium), which is mostly ground cover that likes full sun.
Penstemons, Achillea, most salvias (S. spathacea will do well in part shade), Clarkia, fivespot and Gilia also want sun and will be gone by June. Also, the Achillea and salvias would not like the moisture Mimulus would probably do okay.
Some CA natives that do well in moist shade to part shade include:
Phacaelia, Chinese Houses, Douglas Iris, PCH Hybrid Iris, Polemonium occidentalis, Monardella, Dicentra formosa, Aquilegia formosa, Saturja, to name a few.
For a larger shrubs, look at Ribes sanguineum or thatcherianum, Carpenteria, Holodiscus, and Toyon.

Arctostaphylos definitely won't like the shade OR the moisture. I second Wanda's recommendations of Ribes, Carpenteria or Toyon - perhaps also some of the Mahonias. I don't think it's technically a native, but check out Arbutus x 'Marina' - it's a hybrid of our native madrone, and gives you a lot of the advantages of manzanita (red bark, white flowers) but is much more tolerant of garden conditions.

You might check out Las Pilitas Nursery - all Calif. natives. Their website has excellent growing information on their plants.

My suggestions for a shrub/small tree in moist, part shade location (zone 24) are:

calycanthus occidentalis. (spicebush)
myrica californica (pacific wax myrtle)
philadelphus lewisii (western mock orange)
sambucas racemosa racemosa (red elderberry)
ribes aureum var. gracillimum (golden currant)

Perennials:
aquilegia formosa (western columbine)
artemesia douglasiana (mugwort)
asarum caudatum (wild ginger)
mimulas cardinalis (scarlet monkeyflower)
mimulas guttatus (seep monkeyflower)

And do check out the Las Pilitas Nursery. Might I also recommend the book "California Native Plants for the Garden" ISBN 0-9628505-8-6. An indispensable resource for gardening with native plants.

Wow, thanks for the recommendations to all of you. I do like the idea of Ribes, it has flowers similar to fuschia and the birds will love it. Many of your other recommendations I planted at my parents' home during the last few years, so I can easily make cuttings. I might have to grow some of those full sun species in pots up on our balcony where some spots get full sun year round.

Carpenteria may be nice, too. Some white to brighten up the shady spot. Calycanthus is a nice flower morphology, and I love the fragrance of it. Yerba Buena would be a nice groundcover under the trees by the street, and again, I like that it has fragrance. It will like the fog in Summer, too.

Phacelia campanularia is one of my favorite flowers, the blue color is amazing. I only worry about the kids in the neighborhood touching it, it gave me a pretty bad dematitis a few months ago when I collected seeds from them.

I've been trying to estimate how much sun that area will get in the peak of summer, in June. I think one strip will be filtered/dappled shade, and half of one will be in direct sunlight for a few hours when the sun is highest in the sky.

The Las Pilitas site is basically my encyclopedia for getting info about plants, especially their hummingbird and butterfly plant lists. That, google image searches and the online Jepson manual.

And even though they aren't natives, I've always wanted to grow Hellebores, so maybe that will go in somewhere too.

Thanks again, and happy gardening.
