I have a Nikon coolpix 5000 plus a Nikon coolpix 8800 [ new toy]
and have an AV connection and can play back images while they are
still on the memory card but I am not sure if it is possible to do
this before the image is taken.
What you're talking about is a function called "remote capture". My
experience with it has only been the Canon "A" series cameras (A630,
A640, etc). Canon uses your computer, however, and you actually
control the entire exposure from there. The exposure, once made, goes
directly onto your hard drive bypassing the camera's memory card.
I think several of the SLR type digicams have the funtion as well
but I'm unfamiliar with which.
Unless you do a lot of shots in a single session it is almost as
easy to do a test shot, remove the memory card and view it on your
computer via a card reader, replace the card and finalize the shot.
You can also review your shots right on the camera using the zoom
function to check critical focus in any area of the shot. It all
depends on how large your camera's LCD is - not as handy on the older
