Well done.
I'm Australian so go to the organic topic below and ask for advice on the best soil for Californian home gardeners. There is a landscape supplies place 15 minutes' drive away and I just phone them up and ask the blokes I know there to deliver 5 cubic yards of manure. That is delivered within a day and tipped in my drive. It's an eight-foot circle of manure about four foot high so you need a driveway to leave it on for about four weeks whilst you wheelbarrow it to your beds.
BTW you need a wheelbarrow, spade, rake and fork to start with.
I dump the manure, undiluted, as a three-inch-high topping to all my beds. I leave it there until the rain comes and softens the soil below and then fork it in as I need the bed. Soil is the most important part of gardening so you will be adding compost, leaf mulch, micronutrients, worm wee, fish emulsion and all the organic fertilizers to the soil as time goes by.
As for the tomato and strawberries you have already planted - I would build up a collar of the fertilizer (above) around the neck of the tomato and pepper. I would build the strawberry mound as well and transplant the strawbs into the mound remembering to keep the crown clear of the soil.
Then I would contemplate what else to plant in conjunction with the cook (if that's not you).
Late summer plants (no frosts, harvest to march /april) - potatoes, onion, garlic, leek, beans, carrots, turnips, radish, beets, lettuces, basil, thyme, oregano, fennel, dill, and more. Choose the ones with shortest growing season and some that are all season plants like carrot and lettuce.
Tomatoes, corn, strawbs are the vegetables that taste most like cardboard when shop bought so they are worth growing at home.
Good luck and keep us posted.
