This is a fantastic start for a first season. Those spots look like they are probably insect damage. Try planting some marigolds around the tomatoes next time -- they seem to be pretty good for pushing pests away, and will probably make the mrs happier as well. The most useful thing, if you are in any way a cook, is an herb garden. They're practically no work other than watering, and you'll be using them more and more once you start. It's an encouragement to keep to eating whole foods, too. Parsley, basil, thyme, oregano and chives are what I use most, but it depends on your taste. Grow what you like to eat.
