| This all depends on where you live and what the climate is like. Go to a local store, pick up some seeds, and look at the back of the packet. Most of the information you can learn about growing that crop is on the back; much is learned with experience. Also, you shouldn't be be too interested in huge quantities, otherwise you'll have more work and vegetable on your hands than you'll know what to do with.
I'm a soil scientist and from a soil's perspective; dig a pit in the soil and see how deep down you can go before you hit a rock pan, if there even is one down there. You can't grow deep rooted plants in shallow soils very well at all. Also, unless you have something bigger than a garden, i recommend tilling the soil either with a shovel by digging in deep 6-10 inches and loosening it or getting a hold of a rototiller if you have access to one or are willing to rent one.
As far as costs are concerned, this is up to you. You can buy seeds and grow them and planters and transplant them and have a nice garden for less than twenty bucks or you can buy plants that are already ready for transplanting in addition to getting fancy with other stuff and spend hundreds.
I live in the central valley of california ad my personal favorites are squash's, which yield a lot, so don't plant more too much, tomatoes, which also yield a lot so don't plant too many, and peppers.
If you happen to have any more specific questions feel free to ask.
