For awhile CMOS was considered a lower quality option than CCD, but not any more. Nowadays, they are equivalent. However, since most manufacturers went with CCD in the early years of digital cameras, there are more cameras on the market which use that type of sensor. CMOS has some advantages like using less power (so batteries will last longer) and being less expensive to manufacture, so we'll probably see more CMOS cameras in the future.
VGA (video graphics array) is a computing standard and refers usually to a resolution of 640x480 - this is the resolution of a standard definition TV. in digital cameras it's usually refering to the video mode being able to output at standard definition. Older cameras had really poor video resolution and looked terrible when displayed on televisions.
CMOS ( complimentary metal oxide semiconductor) is a sensor type. Its different to CCD (charge coupled device) and is being used more frequently in high end cameras like SLR's as they draw less power from the camera battery than CCD. CMOS sensors though are typically less sensative to light than CCD's similar size. Both sensor types have advantages and disadvantages and niether is significantly better than the other.
Megapixels is simply the number of dots that make up an image. A sensor is covered in tiny pixel sites - each site has a microlens which gathers light and focuses it on the pixel. These pixels make up the image. Usually the lower the megapixel count the larger the pixel site and the better the low light performance so a 6MP camera typically gives a better quality image in low light than a 12MP camera, but the 12MP records more fine detail.
At this point, they are comparable. For years CMOS was lagging behind CCD in quality, but that is no longer the case. From the standpoint of the manufacturer, CMOS consumes less power and is cheaper to manufacture. I would say that certainly there are more cameras that use CCD than CMOS, but that's simply because most manufacturers went that route to begin with.
