ohhhh, you have tomatoes and peppers already?! drooooool. Envy!
As far as the watering, I'm not on a schedule, really. I check the garden daily and if it's dry (and monsoon storms are not forecast!), I water. If you stick your finger into the dirt, a couple inches down, and it feels dry to the touch, then it needs water. Sometimes the surface can look/feel dry, but you want to check farther down. And, especially for tomatoes, water near the ground, not on the foliage. I find it's pretty much unavoidable that I'll accidentally splash some water on the foliage too, but you don't want to hold the watering can above the entire plant and water from the top.
I admit I've probably done something of a bait and switch with Boyfriend. We've been together for 12 years and it's only the past 3 or so that I've really gotten into gardening. This year I decided to expand what I was growing and I don't think he quite understands why. He is averse to any sort of physical labor and is not handy. We rent so usually this isn't a problem.
