I believe that the Fall Update gave the xbox 360 1080p resolution, but only if you use VGA cables (not through component, I don't believe 1080p is possible through them)
Component does have enough bandwidth for 1080p (my LCD accepts 1080p through VGA, component, HDMI, and DVI)
If your tv can "accept" 1080i but not 1080p, you most likely have a 720p native LCD. If that's the case, 720p should actually look better on your display than 1080i.
1080p does have its advantages, but the 360 doesn't really make much use of it yet, besides HD-DVD playback.

So what if I connect low-definition sources; like s-video or composite? Since its progressive in nature, do both of those render in 480p? Or do I still NEED to have component cables to achieve that resolution? But if the LCD does not display interlacing, is there a difference if say I connected a DVD player with S-video versus component? Would both cables display in 480p?
480p, 720p, 1080i, and 1080p are only possible through Component, VGA, HDMI, DVI, and Scart (<--not sure what exactly what that one supports, it's a euro thing)
S-video and composite (yellow plug) can only do 480i.
Even though LCD's are progressive by nature, they can display 480i images by de-interlacing them with their internal scalers. Some LCD's have issues with this however that make the image not look as good as on a CRT, so most of the time you want to be in progressive scan mode at the highest res your display supports.
The games for the 360 will always be rendered in their default resolution by the GPU (which most of the time is 720p) and then good 'ol Ana (the scaler chip) will scale the image to the appropriate resolution (downscale or upscale, depending on what res you are going to) and output the image via the the a/v multi-out port.
