Welcome!
I'm not much up on DVDs, but you might want to see if some of the better basic magazines, like Fine Cooking or Cook's Illustrated, have some. I know Fine cooking has all their issues for the first 15 years or so on disk.
As for books, even though you have some skills already, you should get
The New Cook by Marry Berry and Marlena Spieler. It has tons of pictures, and very good explanations.
Another couple of books I like for their clarity and breadth are:
Essentials of Cooking by James Peterson
Jacques Pepin's Complete Technique
Probably all are available from Amazon and other booksellers.
Oops, just reread the end of your request.
Vegetables from Amaranth to Zucchini by Elizabeth Schneider is my go-to book for unusual, um, vegetables. She also put out
Uncommon Fruits and Vegetables, which might be hard to find but worth it.
