    Can someone give me a little explanation on the terms below?
    I know my Nikon D40 supports AF-S, but what's that all about?

    AF
    AF-S
    EF
    EF-S

    you need not worry about EF or EF-S as they pertain to canon mounts.

    AF:autofocus lenses for nikon Mount
    AF-S: autofocus lenses for nikon cameras that don't have a built-in autofocus motor (D40 and D40x)

    For DX, I know it is a 3rd party term, I don't know if it's Sigma, Tamron, Tokina, or Quantaray. I don't buy 3rd party things.

    So if I'm sticking to my D40 and want to make my life as easy as possible, I should go with AF lenses?

    If you want to manually focus than yes. The D40 requires the AF-S lenses to autofocus.

    AF-S lenses are the best for your camera. your camera doesn't "support AF-S" like it's a special feature, but rather it HAS to use them (to autofocus) and cannot properly support AF lenses. the D80 can use either one.
