Another good resource, along lines of book that Bob suggested, is the Food network special Wine for the Confused. Hosted by John Cleese, was a great introduction to wine for the new drinker, or review for those who've been drinking for years. He hits on 3 of the most common white and red varietals, at least here in America, as well as words for descrbiing taste, how to buy, how to store, and how just to enjoy wine. Plus just fun to watch, as you'd expect with said host.

"Don't let anyone ever try to tell you what wine you like, because people have different tastes and we shall honor that," he heralds at the start.
I figure that quote sums up attitude he takes for the show pretty well, and I think you'll be able to identify with it too, based on what you've posted here.
