As the PP said, I don't know of a particular kit either. I have a copy of the Bernardin Guide to Home Preserves. There are lots of canning books out there...the only thing I would say on that topic is to make sure you buy a recent book, as there have been some changes over the years as they have learned more about food safety.
Jars: yup, these can be gotten very cheaply, either in places like Goodwill, garage sales, etc. And if you buy them off-season, they are also very cheap brand new. The jars can be bought 2nd hand, but don't buy the lids 2nd hand, for safety reasons. You can find packages of lids anywhere, in the grocery store even, for very little. Depending on the amount of canning you are planning on doing, you might not even have to spend your full budget.
You will also need a little basket to hold your jars while they're in the water bath, and while not absolutely necessary, the tongs made especially for holding hot jars are extremely helpful.
I completely agree with Velochic: it's not difficult at all, but it's very important to do it correctly. When I was learning, I found there was a rather cavalier attitude among my resources (ie older members of my own family). Things like "you don't really need to sterilize the jars, just throw them in a sink full of hot water and dish soap" (no, you really DO need to sterilize the jars), and "pressure canning is not really necessary for meats and low acid foods, just boil the jars for a bit longer in the water."
