Answer
Your HDTV will display the best video image with a true HD input. On Dish, that means springing for an HD receiver or DVR with an HD channel package. You may also need a new LNB installation. You should get pretty good standard-def (SD) reception with your SD receiver, though.
As for the change next year, that only affects those using an over-the-air (OTA) antenna for TV reception. If you have an OTA antenna, your set should pull in excellent HD programming for free right now from the digital transmitters that are already on the air, providing that you're in a location with good OTA reception.

Answer
1) you can use image software to resize or crop the image. Resize means shrinking the whole picture to smaller dimensions. Crop means to trim the outer parts that are not important.
Sometimes a resize will be to another proportion (width to height). This might distort the image.
2) Resolution is the level of fine details. The most common resolution for computer screens is 0.25mm or about 100 pixels (picture elements) to the inch. TV screen resolution depends upon the broadcast system (SD or HD) and the size of the screen. A 32 inch HDTV might have smaller pixels and more to the inch than a 70 inch HDTV, even though both are 1080p or 720p rating for HDTV.
3) More megapixels means the image has more elements to its width and height. It might have 2500x1800 at its highest resolution. That will fill up the camera's memory with only a few pictures. Or it could be taking more pictures at much lower resolution (1024x768). It is the user's choice: how much storage, how important the picture, what it will be used for.
To display on a large screen HDTV that is 1080p, the picture needs not be larger than 1920x1080. If the camera takes that shot, it need not be more than a 2.1 megapixel camera. With 1GB storage, you could store 337 in RAW mode, or 1350 in JPG 100% quality mode.
Where massive megapixel comes handy is in Zoom mode. You could take the 41mp camera and zoom in to the center of the screen, using just 10% of the pixels in the detector. That is a 10X digital zoom with no loss of detail on the HDTV display. Add in the 3X or higher optical zoom of most cameras, and you have a 30X magnification of the center of the picture with the same level of detail on the HDTV.
