1. the 320x240 is not as good as the 640x480. These are resolutions of the pictures you are taking. (the larger the No.s the better quality the picture) If you have the memory choose the better quality one (640 x 480)
2. 640x480 is a higher resolution. It is more for printing out your pictures, so that they come out sharp and clear. 320x240 is lower resolution. It is more for emailing your pictures, so that it doesn't take forever for someone to download them. The picture files are smaller, so you can fit more on a memory card.
3. These are two different resolutions for MOVIE shooting with your SD1000. Your camera will shoot in both 30 frames per second or 15 frames per second. 30 frames per second will give you better video on moving objects. Generally speaking, for internet only, the 320x240 is better because it gives you smaller file sizes and lower resolution--better for uploading/downloading, etc. 640 x 480 is standard definition TV quality (with square pixels), so if you intend to playback on a TV, I'd recommend this size. It has more data, so it'll eat up more memory card space, but it'll also be higher quality. Hope that makes it clear.
4. If all you do is print out 4x6 prints or send jpegs over the Internet, then 320x240 is fine, BUT, the smallest file size for the Canon SD1000 is 640x480 -- NOT 320x240. On this camera, the 320x240 file is for movies at 15fps (frames per second) NOT prints. However, these numbers represent the number of pixels used to make the image. The higher the numbers the bigger the print you can make or be able to crop out pieces of the original image without it looking pixelated (square grain). The higher the numbers used, the more the image files size becomes and uses up your flash memory with less images but higher resolution. The misnomer people have is resolution mean sharpness -- NOT true. A small file size image printed out as a 4x6 full frame compared to a large file size image printed out to a 4x6 full frame will look exactly the same. Only when you begin to enlarge the image will you notice the difference in resolution (the small file will begin to look very grainy -- pixelated with tiny squares or rectangles depending on the type of digital sensor in your camera) -- but sharpness remains the same.
