First of all, welcome to the forum. Glad you are here.
What you do and how you approach the clay problem will depend on your method of gardening. Are you planning on the "traditional" turning a large area and planting rows of crops or are you planning to only do a small intensive plot. Several people on here do containers. Some people try to go organic and some do not. There are many different ways to do things.
Whichever way you go, I agree with adding lots of organic material. I have a similar problem with clay. This next season will be my third season here, growing in a 50' x 75' "traditional" garden. My procedure varies a bit depending on what I am planting and the method I use (transplant, direct seed, raised hill) but I will usually use a hoe to scrape out a trench about 2" to 3" deep, fill it with compost of some sort, mix it up with the clay, then plant in/on top of that.
I also mulch certain plants heavily, usually spreading two or three layers of newspaper around the plant and covering it with grass clippings or well dried wood chips to hold the newspaper in place. All that organic material gets worked into the ground the next season plus the benefit I get from mulching during the growing season.
Speaking of growing season, I'll give you these three links to help determine yours. I'm right on the border so I get three different zones when I use these, 6, 7, and 7A, so I figure anything that is good for all these zones 5, 6, 7 and 8 has a chance here.

I'd suggest visiting your county extension agent's office and see which phamplets and bulletins they have you might be interested in. You should be able to find them in the phone book under county government. Here in Arkansas, I can get a different brochure for each crop, telling me the time to plant, type of soil conditions they like, which varieties do best, how to harvest, etc. One of the more useful is a calendar telling me what to do each month in my area. For example, in December I can plant garlic, lettuce in a cold frame, certain salad greens, and English peas, lime the soil if it needs it, get a soil test, order catalogues, and order seeds. The list for April is much longer.
Another suggestion. If you plan on sticking around this forum, and I hope you do, you might want to go to your profile and show your general area and zone. It does help to answer some questions and I think it adds a nice personal touch when we communicate.
