I love "A Cook's Tour" but it's not on very often. I also love both "40 Dollars a Day" (Rachel Ray is so cute!), and "Good Eats". And, though it's not really my style, "Paula's Home Cooking" is very soothing to watch.
I'm not a big fan of Emeril - his recipies, for the most part, are so complicated, and I just don't find his on-air demeanor appealing. I once made his sweet-potato brownies, and while they were awesome, it took THREE HOURS to make!!!
The Food Network web site is a wonderful resource for recipies - you can find just about anything on there. It and
www.epicurious.com are the first places I go to find stuff (ignoring all the cookbooks I have in my cabinet...I have a small, uh, cookbook buying problem).
