I've been canning for a few years, and I taught myself how to do it by reading online. I started with a hot water bath canner, and now have a pressure canner.
Unlike a previous poster, I have canned with my children around. They enjoy helping with the prep work- peeling apples, washing veggies, cutting veggies, picking produce, shelling peas and beans, etc. Usually the kids are running in and out of the house as I'm canning- if they are underfoot, I just send them back outside. Yes, it is easier to can without distractions
But if you're going to be canning a large amount of produce, it's very likely that you'll need to be working while your kids are around.
I found that googling "canning xxx" yeilded many good links. When canning something new, I always read several different sites so that I'd be sure I was getting good info. I'd follow the procedures suggested by the majority of the sites. There are many good state university extension sites. For pictures, I like this site:

I'll also give you another piece of advice that is probably obvious to everyone but me. Only can the foods that you actually like to eat. So what if everyone else cans pickled beets- if you don't like pickled beets, don't make them! The things I usually can each year:
green beans
tomato sauce, tomato paste
spaghetti sauce
pizza sauce
salsa
applesauce
jam/jellies
rhubarb sauce
Things I freeze:
broccoli
sweet peas
spinach
