Wow, green horns. Well, for the first part of your first question you do want to get a HD decoder for your cable service. You will at the very least need a component conection(for 1080i) with this. As for the second part, the HD channels that are available will take advantage of you 16:9 screen. Unfortunatly, you will need to set the display with the black bars on the sides for regular channels, otherwise you will get a stretched picture.
The best connections for your tv are the DVI, HDMI and PC inputs. You should invest in a DVD player which can upconvert 480p to 720p or even 1080i(need a DVI or HDMI cable). Try and avoid using the coaxial, composite and s-video inputs for any of your equipment if possible.
As for the widescreen dvd movies, since you have a 16:9 display you are taking advantage of the widescreen output of the dvd's with this feature. You will come across DVDs with the original theatre aspect(lotr for example) which are even wider than 16:9 and still require the bars on the top and bottom. Some DVDs are formatted to 16:9(1.78) but, for movies like star wars or LOTR they keep the original aspect(2.35:1).
The thing is DVD comes in a variety of formats including 1.33, 1.78, 1.85, 2.00, 2.35, 2.4, 2.5, and so on. So there is no universal standard for the rectangular shape of a video picture, but in my opinion it's still better to watch these on a widescreen display instead of a regular 4:3 tv(1.33).
Please feel free to ask more questions. I hope I didn't confuse you even more.
