Looks like Felpro B45682 contains both cam plugs and valve cover gaskets for 18.99 @ Autozone (they actually beat O'Reilly's price this time by $1).

My valve cover gaskets are brand new, however, so I'm not sure if I want the kit with everything or not. The plugs are 4.99 each at O'Reilly, so it would save me $9. But, if I do end up needing the valve cover gaskets, they won't have them in stock. So, what to do? I only siliconed the valve cover gaskets in the "corners" (next to the plugs). Shouldn't be a problem reusing them, I would think? Anybody?
